Embodiment 1

[0020] See figure 1 , a configurable caching system of the present invention, including a front-end scheduler, a front-end cache server, and a front-end scheduler, here refers to seven-layer application proxy software widely used in web development, including nginx, haproxy, etc. are very efficient For the front-end scheduler, nginx is preferred in the present invention.

[0021] Relevant location rules and embedded script Lua language are configured in the front-end scheduler. The present invention uses embedded script Lua language programming to eliminate possible interference with the cache through url rewriting technology and custom header domain values ​​in the front-end scheduler. factor to maximize the cache hit rate.

[0022] The configurable caching method of the present invention is implemented by the above-mentioned configurable caching system, and includes at least the following steps:

[0023] (1) The front-end scheduler forwards the request, judges the request,...

Embodiment 2

[0047] Taking the login user language version distinction as an example, the present invention is divided into proxy service configuration logic and response matching logic.

[0048] An example of proxy service configuration logic is as follows:

[0049] rewrite / demo.php?test=abc / demo.php last; #Use internal jump to achieve the purpose of modifying url

[0050] set $deflang en; #default value

[0051] set_by_lua $flang'

[0052] local l = ngx.req.get_headers()['Accept-Language']

[0053] return l

[0054] ';

[0055] if ( $flang ~ 'zh' ) {#Browser logic--request header Accept-Language

[0056] set $deflang zh;

[0057]}

[0058] if ( $cookie_deflang ) {#cookie logic --deflang

[0059] set $deflang $cookie_deflang;

[0060]}

[0061] fastcgi_param HTTP_VARY_DEFLANG $deflang; #Generate request header Vary-Deflang.

[0062] The response matching logic is as follows:

[0063] header('Vary: Vary-Deflang').

[0064] The above example only shows the matching and rewritin...

Abstract

The invention provides a configurable caching system and method. The system comprises a front-end scheduler and a front-end cache server. A related location rule and an embedded script Lua language are provided in the front-end scheduler. According to the system and the method provided by the invention, by using url rewriting technology and a self-defined header field value in the front-end scheduler, factors that may interfere with caching are eliminated, thereby ensuring a hit rate of caching to a maximum extent; it is ensured that different URLs are cached according to same logic; meanwhile, it is ensured that login users are provided with separate caching logic for a same URL.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a front-end caching system and method. Background technique [0002] Cache technology is ubiquitous in computer systems, from computers to various routing devices, from software implementation to hardware implementation, a well-designed cache system can greatly improve the response speed of the system and improve the user experience. In Internet applications, the cache system is divided into back-end caches such as memcache and redis, and front-end cache systems such as Squid, Varnish, Nginx, and Apache Traffic Server. Regardless of the front-end cache or the back-end cache, adapting to business needs and improving the cache hit rate are the most important pursuits. [0003] Front-end cache service refers to the use of CDN technology, using Squid, Varnish, Nginx, Apache TrafficServer, etc. as front-end cache to provide cache services described in the HTTP protocol. [0004] The HTTP...
