OpenLiteSpeed WordPress cache mysteriously not working

The OpenLiteSpeed web server (OLS) and LiteSpeed Cache for WordPress (LSCWP) plugin provide a great way of both speeding up WordPress and handing large numbers of visitors. OLS is an open source derivative of the LiteSpeed Web Server (LSWS), which delivers most many of the key features, including the high performance LiteSpeed Cache (LSCache).

OpenLiteSpeed OCSP stapling with Comodo PositiveSSL

OpenLiteSpeed supports OCSP stapling, which helps web browsers check the revocation status of an SSL certificate without having to connect to the Certificate Authority’s OCSP servers and so can speed up the SSL connection process. In order to enable OCSP stapling, first we need to construct the intermediate certificate chain which OpenLiteSpeed will use to cryptographically verify the response from...

Commercial SSL certificates with SolusVM

When you install SolusVM it generates a self signed SSL certificate for use with the end user control panel and admin interface, however it would be wise to purchase a certificate from a commercial certificate authority to prevent man in the middle attacks (and get rid of annoying browser warning messages).

Convert SolusVM from Lighttpd to Nginx

Historically the brilliant SolusVM VPS control panel have used the Lighttpd web server on their master and slave nodes, however it is now possible to use the popular Nginx as an alternative web-server.
