Purpose: To cache the static files of the Nginx server. As css,js,htm,html,jpg,gif,png,flv,swf, these files are not updated frequently. Easy caching to ease server pressure.Implementation: Nginxproxy_cache can cache the user's request to a local directory, when the next request can be directly transferred to the cache

Gzip Compression OverviewWeb pages in the server side after gzip or other format of the compressed output significantly reduced content-length bytes, when the access to millions, these reduced bytes will become objective traffic to save, thereby reducing the pressure on the server and the speed of the Web page access;PrincipleWhen the client sends an HTTP request to the server, it has a accept-encoding header in the request header, which tells it what kind of compressed file it can receive from

What is the difference between the Varnish/squid/nginx cache? SQUID is the most comprehensive, but the architecture is too old, performance is not bad varnish is memory cache, speed first-class, but the memory cache also limits its capacity, cache pages and pictures are gene

Browser local cache, that is, when the browser loads a Web page, you can cache some of the content of the Web page, the local content will be loaded again, this can greatly improve the speed of access to the site. For the server side, this will also greatly save network resources.Browser caching relies on the Expires command output header to achieve:syntax: Expires [Time|epoch|max|off]Default value: Expires

Syntax: Expires [Time|epoch|max|off]Default value: Expires offScope: HTTP, server, locationUse this directive to control the headers of "Expires" and "Cache-control" in HTTP replies (as a function of controlling page caching).You can use a positive or negative number in the time value. The value of the "Expires" header is obtained by adding the time value you set for the current system.The epoch specifies a value of "Expires" of 1 January, 1970, 00:00

Browser cache is used to accelerate browsing and save network resources. The browser stores recently requested documents on the user's disk. Nginx can use the expires command to set the browser header. Syntax: expires [time | epoch | max | Off] Default Value: expires off Scope: HTTP, server, location This command can be used to control the header labels of "expires" and "

In the beginning, the Nginx environment was built to realize the distributed cluster simply for load balancing. It is now possible to use the Nginx caching mechanism to optimize the corresponding speed. The following is a description of Nginx images, CSS, JS cache.#图片缓存时间设置location ~. *.

In the previous article, it was mentioned that the Nginx memcached module application scenario, mainly as a file cache. Then a problem is found, when large files are cached in a byte array, the cached data is compressed, which can cause problems when reading.(This article welcomes reprint, respect for others labor, reproduced please specify the Source: http://blog.csdn.net/poechant/article/details/7177603)T
