Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention aims to provide a web page request system and a web page request method based on load balancing, which reduce the resource consumption of a server.
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
Currently, users (clients) are directly connected to a web server, and if the web server is down, the users naturally have no way to access. In addition, if many users attempt to access the server at the same time, the limit that they can handle is exceeded, there may be situations where the loading speed is slow or no connection at all. The present invention can alleviate this failure by introducing a load balancer (load balancing module) and multiple additional web servers. Typically, all backend servers will be guaranteed to provide the same content so that the user can receive consistent content regardless of which server responds. Additional multiple web servers may also share the load, relieving individual web servers of stress, and thus handling more user requests.
Example 1
As shown in FIG. 1, the web page request system based on load balancing comprises a client, a load balancing module and a server; the client is connected with the load balancing module and the server respectively, and the load balancing module is connected with the server.
The workflow of the web page request system based on load balancing is shown in figure 3.
The client is used for sending a web page request message to the load balancing module.
The load balancing module is used for sending the request web page message to the server and determining whether the response web page corresponding to the request web page message is compressed or not.
The server is used for sending a response web page to the load balancing module after receiving the request web page message.
The load balancing module is further used for compressing the response web page and sending the compressed response web page to the web browser of the client when the response web page is determined to be compressed; and when the response web page is determined not to be compressed, sending the response web page to the web browser of the client.
According to the invention, the web page compression module is added in the load balancing module, and the compression operation is carried out on the web page of the specified type, so that the purposes of saving the Internet bandwidth resource and reducing the pressure of the web server are achieved.
The load balancing module comprises a compressed web page type list; the compressed web page type list is used for storing web page types preset for compression.
In the configuration page of the load balancing module, the web page types needing to be compressed are configured by compressing the web page type list, and the web page types are as follows: * Html/. Js/. Txt/. Css.
The load balancing module is used for assigning a compression identifier corresponding to the request web page message to be 1 when the web page type corresponding to the request web page message exists in the compression web page type list; and when the web page type corresponding to the request web page message does not exist in the compressed web page type list, assigning the compression identifier corresponding to the request web page message to be 0.
The load balancing module is used for compressing the response web page by adopting a gzip algorithm.
The load balancing module is further configured to send the compression identifier to the client.
And the client is used for decompressing the corresponding compressed response web page and displaying the decompressed response web page through a web browser when the received compression identifier is 1.
The load balancing module is connected with a plurality of servers. Each server provides the same content, relieving the individual web servers of stress, and thus handling more user requests.
The load balancing device adopted by the load balancing module can be software or special hardware equipment.
Wherein the software load balances the open source of the ngix (https:// www.nginx.com /).
The professional hardware load balancing providers are: f5 (https:// www.f5.com /) and Hongdi technology, F5 is a United states corporation.
Today, slightly scaled websites (including shopping websites and ticketing websites, etc.) must use load balancing techniques, smaller scale websites may use software load balancing, and larger websites may use specialized hardware load balancing.
The server (web server) refers to a website server generally, refers to a program of a certain type of computer residing on the Internet, can process requests of web clients such as a browser and return corresponding responses, and can also place website files for browsing worldwide; data files may be placed for worldwide download.
The web page refers to a page file returned to the client by the web server for analysis by a browser of the client and display to a user.
The invention discloses a workflow of a web page request system based on load balancing, which comprises the following steps:
step1, the web browser of the client accesses the load balancing module and sends a request for a web page (webage1.html) to the load balancing module.
And Step2, after the load balancing module receives the request, judging the type of the requested web page. According to the pre-configuration, it is determined whether the requested response web page requires a compression operation.
Step3, the load balancing module forwards the request of the client to the back-end web server.
Step4, the web server returns a response page to the load balancing module. This response web page (webage1. Html response web page) contains content that needs to be compressed. The content to be compressed includes: pictures, audio and video, text and the like to be displayed on the web browser.
Step5, according to the judging result of Step2, if the web page needs to be compressed, the web page is compressed. Replacing the response web page with the compressed content after compression; if the page does not require a compression operation, it is forwarded directly to the client.
Step6, adding a Content-encoding:gzip field in the HTTP response. This field indicates that the current response page data is compressed by the gzip algorithm, and the web browser recognizes this field and decompresses the data. And then forwarding the compressed response page to the client.
Example 2
The invention also discloses a web page request method based on load balancing, which is applied to the web page request system based on load balancing described in the embodiment 1.
The client sends a request web page message to the load balancing module.
The load balancing module sends the request web page message to the server and determines whether the response web page corresponding to the request web page message is compressed.
And the server sends a response web page to the load balancing module after receiving the request web page message.
The load balancing module compresses the response web page when the response web page is determined to be compressed, and sends the compressed response web page to the web browser of the client; and when the response web page is determined not to be compressed, sending the response web page to the web browser of the client.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other. For the method disclosed in the embodiment, since it corresponds to the system disclosed in the embodiment, the description is relatively simple, and the relevant points refer to the system part.
