Description

Method, system, network server, browser and GSLB for acquiring webpage

Technical Field

The present application relates to the field of communications network technologies, and in particular, to a method, a system, a web server, a browser, and a GSLB for acquiring a web page.

Background

With the development of communication network technology, various information can be acquired by browsing various web pages provided by various websites. In order to increase the web page opening speed, a new layer of Network architecture CDN (Content Delivery Network) is added to the existing Internet (Internet), and the Content of the web page is delivered to the Network edge closest to the user through the CDN, so that the user can obtain the Content of the web page nearby, and the response speed of the user to access the web page is increased. The existing web page generally consists of a web page basic frame and web page reference contents (such as a style sheet file CSS, a JavaScript script, a picture, a video, and the like), in order to facilitate CDN acceleration, the web page reference contents adopt a domain name different from that of the web page basic frame, and meanwhile, in order to avoid a restriction of concurrent access of a single domain name of a browser, different web page reference contents adopt different domain names, for example: the domain names of the web page reference contents include static. Therefore, when acquiring a web page, it is necessary to acquire a web page basic frame constituting the web page according to a domain name of the web page basic frame constituting the web page, acquire each web page reference content constituting the web page according to a domain name of each web page reference content constituting the web page, and combine the web page basic frame and each web page reference content to obtain the web page.

Referring to fig. 1, the conventional specific process for acquiring a web page is as follows: the browser acquires a web Domain Name (e.g., www.example.cn) of a pre-visited web page, queries that an IP (Internet Protocol ) address corresponding to the web Domain Name is not cached locally (the browser itself and an Operating System (OS)), and then sends a Domain Name resolution request (1a) carrying the web Domain Name to a Local DNS (Local Domain Name Server). The local DNS receives the domain name resolution request, inquires that the local DNS does not cache the IP address corresponding to the webpage domain name, acquires the IP address corresponding to the webpage domain name through a Root DNS (Root DNS) and a Global Server Load Balance (GSLB), and returns the IP address corresponding to the webpage domain name to the browser (1 b). The browser establishes connection with a Web Server (Web Server) of the pre-accessed Web page according to the IP address corresponding to the Web page domain name, and sends an HTTP (Hyper Text Transfer Protocol) request (2a) carrying the IP address to the Web Server. The web server receives the HTTP request, generates and returns a web page basic frame (2b) corresponding to the IP address to the browser. The browser receives a webpage basic frame returned by the network server, analyzes the webpage basic frame to obtain domain names of a plurality of webpage reference contents, initiates a domain name analysis request of the domain name carrying the webpage reference contents (each time the domain name analysis request carries the domain name of one webpage reference content), and obtains the IP address (similar to 1a and 1b) of the webpage reference contents. The browser requests the web reference content from a corresponding web reference content server (e.g., picture reference content server) according to the IP address of the web reference content (3 a). The web reference content server returns the web reference content to the browser (3 b). And (3) repeating the steps 1a,1b, 3a and 3b for multiple times (the domain name of the webpage reference content is repeated for multiple times), acquiring all webpage reference contents contained in the pre-accessed webpage by the browser, and combining all the webpage reference contents with the webpage basic frame to obtain the webpage.

In the existing method for acquiring the webpage, when the webpage contains a plurality of webpage reference contents, a domain name resolution request needs to be initiated for a plurality of times, the steps (1a,1b, 3a and 3b) are repeated for a plurality of times, the time is long, the efficiency of acquiring the webpage is low, and the webpage loading is slow.

Description of the embodiments

The following is a further illustration of the implementation of the method of the present application in one embodiment. As shown in fig. 2, a flowchart of a method for acquiring a web page according to an embodiment of the present application is shown, where the method includes:

s101: and acquiring the HTTP request carrying the first IP address.

The HTTP request is initiated after the browser acquires a first IP address corresponding to a webpage domain name of a pre-access webpage.

Specifically, in order to facilitate the subsequent request GSLB to resolve domain names of all web page reference contents, the HTTP request may further carry a GSLB address, that is, the HTTP request carrying the first IP address is obtained, which includes: and acquiring the HTTP request carrying the first IP address and the GSLB address. The GSLB address can be a GSLB address used by the browser in the process of acquiring the first IP address corresponding to the webpage domain name of the pre-access webpage, and the used GSLB address is recorded by the browser in the process of acquiring the first IP address corresponding to the webpage domain name of the pre-access webpage and then is carried in the HTTP request to be sent to the local.

S102: and inquiring the webpage basic frame corresponding to the first IP address.

Specifically, the corresponding relationship between the IP address and the web page basic frame may be preset, and after the first IP address is obtained, the web page basic frame corresponding to the first IP address is obtained by querying the corresponding relationship between the preset IP address and the web page basic frame.

S103: and analyzing the webpage basic frame to obtain the domain names of all webpage reference contents corresponding to the first IP address.

Specifically, the web page can be obtained only by combining the web page basic frame with all the web page reference contents, and the domain names of all the web page reference contents required to be used in the web page basic frame can be obtained by analyzing the web page basic frame.

S104: and sending a domain name resolution request to a global load balancing server GSLB, wherein the domain name resolution request carries domain names of all webpage reference contents.

Specifically, after receiving the domain name resolution request, the GSLB resolves the domain names of all the web page reference contents, and obtains, in combination with the IP address of the local CDN and the scheduling algorithm of the GSLB itself, the second IP address of each web page reference content corresponding to the domain name of each web page reference content in the domain names of all the web page reference contents.

The domain name resolution request can also carry a user end IP address of a browser which initiates the HTTP request, correspondingly, after the GSLB receives the domain name resolution request, the GSLB resolves the domain names of all the webpage reference contents, and obtains a second IP address of each webpage reference content corresponding to the domain name of each webpage reference content in the domain names of all the webpage reference contents by combining the user end IP address and a scheduling algorithm of the GSLB.

Specifically, since the local link is the user-side IP address of the browser that initiates the HTTP request, that is, the real IP address of the user (if the user is linked to the local via another proxy server, the real IP address of the user can be obtained via the HTTP header X-Forward-For), the real IP address of the user can be locally transferred to the GSLB.

Specifically, GSLB may perform resolution in combination with the user side IP address when resolving domain names of all web page reference contents, so that an optimal second IP address (i.e. an IP address closest to the "edge" of the network of the user) of each web page reference content may be obtained because the user side IP address is the real IP address of the user who has visited the web page in advance. Because the second IP address of each webpage reference content is obtained by the GSLB according to the real IP address of the user, the uncertainty of the prior art that the IP address of the local DNS is sent to the GSLB for reference analysis can be avoided.

Specifically, when the HTTP request in S101 further carries a GSLB address, the sending of the domain name resolution request to the global load balancing server GSLB by the HTTP request includes:

Specifically, when the HTTP request in S101 does not carry the GSLB address, sending a domain name resolution request to the global load balancing server GSLB includes:

That is, GSLB configuration information may be preset locally, and a local corresponding GSLB address may be obtained by querying the local GSLB configuration information.

Specifically, sending a domain name resolution request to the global load balancing server GSLB includes:

sending a domain name resolution request to the global load balancing server GSLB by using an EDNS (Extension DNS) method or an HTTP method.

S105: and acquiring a second IP address of each webpage reference content from the GSLB, and sending the webpage basic frame and the second IP address of each webpage reference content to the browser so that the browser acquires the webpage for displaying. Specifically, after obtaining the second IP address of each web page reference content from the GSLB, the web page base frame and the second IP address of each web page reference content may be wrapped in an HTTP response returned to the browser.

In particular, it may be wrapped in a custom HTTP header, for example: X-GSLB-INFO img01.excdn. cn,60, a, 223.5.6.7; img02.excdn. cn,60, a,223.5.6.8| 223.5.6.9. Or packaged in web page HTML, for example, < meta name ═ X-GSLB-INFO "content ═ img01.excdn.cn,60, a, 223.5.6.7; img02.excdn. cn,60, a,223.5.6.8|223.5.6.9 "/>.

And, a plurality of parsing results can be divided by using semicolon (;); comma (,) is used to segment multiple fields in the same parsing result, and the sequence of the fields in the above example is: domain name, TTL, record type and analysis result; the plurality of analysis results are divided by vertical dashed lines (|). Any other feasible manner can be adopted, and the method is not limited.

Specifically, the second IP address of the web page basic frame and the second IP address of each web page reference content are packaged into an HTTP response returned to the browser, and after the browser receives the HTTP response, the second IP address of the web page basic frame and each web page reference content may be extracted from the HTTP response by a browser plug-in, an ActiveX plug-in, a client agent, and the like. Moreover, the extracted web page basic frame and the second IP address of each web page reference content can be saved in a browser DNS cache, an operating system DNS cache, or a hosts file, etc. through a browser plug-in, an ActiveX plug-in, a client agent, etc., so that when a subsequent user accesses the same web page, the browser plug-in, the ActiveX plug-in, the client agent, etc. can obtain the second IP address of each web page reference content from the browser DNS cache, the operating system DNS cache, or the hosts file, etc., directly initiate a request to the relevant second IP address, and skip the process of DNS resolution.

Specifically, the browser obtains each webpage reference content from each webpage reference content server corresponding to the second IP address of each webpage reference content, and combines the webpage basic frame with each webpage reference content to obtain a webpage.

According to the method for acquiring the webpage, after the HTTP request carrying the first IP address is acquired, the domain names of all webpage reference contents corresponding to the first IP address are acquired, the domain name resolution request is directly sent to the global load balancing server GSLB, when the webpage contains a plurality of webpage reference contents, the domain name resolution request does not need to be initiated for many times, the time for acquiring the webpage reference contents is short, the efficiency for acquiring the webpage is improved, and the webpage loading speed can be accelerated. The real IP address of the user is used as a scheduling basis, and the scheduling accuracy is greatly improved. The DNS resolution is realized through the network server instead of the traditional client mode, the resolution time between the network server and the GSLB is superior to the time for initiating the resolution by the client under the common condition, and the webpage loading speed can be improved.

As shown in fig. 3, a flowchart of a method for acquiring a web page according to an embodiment of the present application is shown, where the method includes:

s201: and acquiring a first IP address corresponding to the webpage domain name of the pre-access webpage.

S202: and sending an HTTP request carrying the first IP address to a network server.

Specifically, after receiving the HTTP request, the network server queries a web page basic frame corresponding to the first IP address, analyzes the web page basic frame to obtain domain names of all web page reference contents corresponding to the first IP address, and sends a domain name resolution request to the global load balancing server GSLB, where the domain name resolution request carries the domain names of all web page reference contents.

Specifically, after receiving the domain name resolution request, the GSLB parses the domain names of all the web page reference contents, and obtains the IP address of each web page reference content corresponding to the domain name of each web page reference content in the domain names of all the web page reference contents by combining the IP address of the local CDN and the scheduling algorithm of the GSLB.

Specifically, the domain name resolution request also carries a local user end IP address, and accordingly, after receiving the domain name resolution request, the GSLB parses the domain names of all the web page reference contents, and obtains the IP address of each web page reference content corresponding to the domain name of each web page reference content in the domain names of all the web page reference contents by combining the user end IP address and the scheduling algorithm of the GSLB itself

S203: and receiving a webpage basic frame sent by the network server and a second IP address of each webpage reference content obtained by GSLB forwarded by the network server.

S204: and acquiring each webpage reference content from each webpage reference content server corresponding to the second IP address of each webpage reference content, and combining the webpage basic frame with each webpage reference content to obtain the webpage.

Referring to fig. 4, acquiring a first IP address corresponding to a domain name of a pre-visited web page includes:

s201 a: and acquiring the webpage domain name of the pre-visited webpage.

S201 b: inquiring whether a first IP address corresponding to the webpage domain name and a GSLB address are cached locally, if not, executing S201 c; otherwise, S201e is executed.

S201 c: sending a domain name resolution request carrying a webpage domain name to a local DNS, so that the local DNS obtains a first IP address corresponding to the webpage domain name and a GSLB address after receiving the domain name resolution request.

Where the local DNS is typically configured by the operator of the network used by the user.

Specifically, referring to fig. 5, after receiving the domain name resolution request, the local DNS acquires a first IP address corresponding to the web page domain name and a GSLB address, including:

s201c 1: the local DNS queries whether the local DNS caches the first IP address corresponding to the web page domain name and the GSLB address, and if so, executes S201c 2; otherwise, S201c4 is executed.

S201c 2: the local DNS determines whether the cached first IP address corresponding to the web page domain name and the GSLB address are valid, and if yes, performs S201c 3; otherwise, S201c4 is executed.

When the cached first IP address corresponding to the webpage domain name and the caching time of the GSLB address do not exceed a preset valid time threshold, the cached first IP address corresponding to the webpage domain name and the GSLB address are valid, and otherwise, the cached first IP address corresponding to the webpage domain name and the GSLB address are invalid.

S201c 3: the local DNS returns the cached first IP address corresponding to the web page domain name and the GSLB address to the local (specifically, the browser), and then ends.

S201c 4: the local DNS sends a domain name resolution request carrying a webpage domain name to a Root domain name server (Root DNS), and the Root DNS obtains an authorized domain name server.

Specifically, the root domain Name Server generally does not provide a (Address) record resolution service for a specified domain Name, but returns an NS (Name Server) record of the relevant domain Name (e.g., example. cn), where the NS record is a domain Name Server record for specifying which DNS Server the domain Name is to be resolved by, and instructs the local DNS to request resolution from the Server of the relevant NS record.

S201c 5: the local DNS obtains the IP address of the GSLB through the authorized domain name server, and the GSLB analyzes the webpage domain name carried in the domain name resolution request to obtain a first IP address corresponding to the webpage domain name.

Specifically, the authoritative domain name server may designate itself as GSLB, or may designate other servers as GSLB.

The GSLB determines which CDN node is used to optimally access the web page according to the request source IP address (the IP address of the local DNS) or according to the user-side IP address, and uses the IP address of the determined CDN node as the first IP address corresponding to the web page domain name.

S201c 6: and the local DNS returns the IP address of the GSLB obtained by the authorized domain name server and the first IP address corresponding to the webpage domain name obtained by the GSLB to the local, caches the IP address of the GSLB and the first IP address corresponding to the webpage domain name in the local DNS, and then ends.

And caching the IP address of the GSLB and the first IP address corresponding to the webpage domain name in a local DNS for the next same query request.

S201 d: receiving a first IP address corresponding to a web page domain name returned by the local DNS, and a GSLB address, and then executing S202.

Correspondingly, S202 sends an HTTP request carrying the first IP address to the network server; after receiving the HTTP request, the network server queries the web page basic frame corresponding to the first IP address, analyzes the web page basic frame to obtain domain names of all web page reference contents corresponding to the first IP address, and sends a domain name resolution request to the global load balancing server GSLB, including:

sending an HTTP request carrying a first IP address and a GSLB address to a network server; after receiving the HTTP request, the network server queries the webpage basic frame corresponding to the first IP address, analyzes the webpage basic frame to obtain domain names of all webpage reference contents corresponding to the first IP address, and sends a domain name analysis request to the global load balancing server GSLB corresponding to the GSLB address.

S201 e: judging whether a first IP address corresponding to the webpage domain name cached locally and a GSLB address are effective, if so, executing S201 f; otherwise, S201c is executed.

Specifically, the browser first determines whether to cache a record of a first IP address corresponding to the web page domain name in a local browser DNS cache, and if so, determines whether the cached first IP address corresponding to the web page domain name is valid, and if so, executes S201 f; if the first IP address record corresponding to the web page domain name is not cached in the local browser DNS cache, or the cached first IP address corresponding to the web page domain name is invalid, the browser determines, through the operating system, whether the record of the first IP address corresponding to the web page domain name is cached in a hosts file (in Linux operating system/etc/hosts, in Windows operating system% SystemRoot% \ system32\ drivers \ etc \ hosts) of the local operating system, if so, determines whether the cached first IP address corresponding to the web page domain name is valid, and if so, executes S201 f; if the record of the first IP address corresponding to the domain name of the web page is not cached in the hosts file of the native operating system, or the cached first IP address corresponding to the domain name of the web page is invalid, S201c is performed.

When the caching time of the cached first IP address corresponding to the webpage domain name does not exceed a preset effective time threshold, the cached first IP address corresponding to the webpage domain name is effective, and otherwise, the cached first IP address corresponding to the webpage domain name is invalid.

S201 f: a first IP address corresponding to a domain name of a web page, which is locally cached, and a GSLB address are obtained, and then S202 is performed. .
