Mod_Expires Configuration In Apache
mod_expires is a module which runs on the Apache web server. It allows manipulation of the cache control headers to leverage browser caching. What this means more specifically is that you will be able to set values on how long the image will be stored by the browser when a client makes a request. This […]
WebP Image Conversion On A Linux Server
WebP is a new image format that provides a lossless and lossy compression on PNG and JPEG file types. It was developed by Google resulting in up to 80% smaller image size. It is supported on all most all modern browser versions. You can use Nginx and Apache to determine if this format is supported […]
Galera Cluster MariaDB Configuration On CentOS 7
Galera cluster is a true multi-master MySQL cluster using synchronous replication. It allows for any of the nodes to be used as a master or all of them as well as providing automatic node joining and node removal. The multi-master configuration is very different from the typical master-slave configuration done with MySQL servers and […]
Install mod_deflate on Apache
Mod_deflate is an apache module. Prior to having mod_deflate it was mod_gzip. Post apache 2.0 mod_deflate is used, it provides a slightly better compression than mod_gzip. It allows the size of certain file types to be compressed which in-turn allows clients to be able to download these files faster. This will cause the site itself […]
Nginx Browser Caching
You can use Nginx to Set cache expiration times to leverage browser caching for the user requesting specific file types. This will cause the browser to retain the downloaded image until the length of the expires header. This will cause faster page time loads on each subsequent request performed by the end user. Prerequisites: You […]
Nginx Caching for WordPress using fastcgi_cache
Caching PHP requests can dramatically reduce server resources per request and make the pages load time decrease substantially. In this tutorial we are going to utilize the fastcgi_cache functions in nginx to cache PHP requests making it. This tutorial assumes you have the following already completed on your server: Nginx installed, if you do not […]
Install The ngx_cache_purge Module In Nginx
Ngx_cache_purge is a module which will allow the fastcgi_cache, proxy, SCGI and uWSGI caches to have content purged from them. The caches allow precompiled code to be served as opposed to running a new version each time. This can greatly reduce the amount of processing power per page request. This specific module allows that cached […]
