nginx cache

The most obvious advantage of using cache for web pages is that it reduces page loading time and server load.Whether the browser uses the cache or how long it takes to cache is controlled by the server. When a browser requests a webpage (or other resources), some fields in the response header returned by the server indicate the key information about the cache.Cac

The 1.nginx configuration is as follows:location ^~ /images/ {set $memcached_key "$uri"; #用URI作为key去memcached中去读取内容memcached_pass 127.0.0.1:11211;memcached_connect_timeout 5s;memcached_read_timeout 5s;memcached_send_timeout 5s;memcached_buffer_size 32k;error_page 404 502 504 = @fallback;}location @fallback {proxy_pass http://backend;}2. Use PHP to write a picture to memcached:$pic = file_get_contents(‘./test.jpg‘);$memcache = new Memcache;$memcache->c

Nginx is a good tool for processing static content. although Apache occupies more memory and has a poor performance, it has been relatively stable. However, Nginx FastCGI may sometimes encounter a 502BadGateway error. An optional method is to use Nginx as a front-end proxy to process static content and forward dynamic requests to backend Apache. NginxServer is co

This cgi script is written in perl and used to clean up multiple nginx cache servers. Usage: place the script on a web server that can execute the cgi program. Open the browser to access this script and enter the CSS or image address to be cleaned up. If you want to clear multiple caches, enter one address in one line. Code :#! /Usr/bin/perlUse strict;Use warnings;Use CGI;My $ req = new CGI;Print $ req-> he

The Cache-control of the HTTP protocol specifies the caching mechanism that requests and responses follow.Setting Cache-control in a request message or response message does not affect the caching process in another message processing process.The cache instructions for the request include No-cache, No-store, Max-age, M

In most cases, our website uses a database as a container for storing site data. When you execute an SQL query, the typical process is: connect to the database-> prepare an SQL query-> send a query to the database-> get the database return result-> close the database connection. However, some data in the database is completely static or infrequently changed. The cache system caches the SQL query results to a faster storage system for storage, this avo

The performance of the project has been at the lower-and lower-level and has been exploring. Since the WCF segment was optimized in the past few weeks, the speed has improved significantly. HoweverProgramIt is not an ideal requirement, so we must continue to work hard! I. Situation Some time ago, we found that multiple clients frequently obtain the same data when they connect to the server for the first time. That is to say, each client needs to search for the same data in the database, it i
