This seems to be the week of the Rewrite Engine for me as this is the second semi unique modification I have needed to make to one of our servers rewrite rule sets. This time we have a site where all traffic destined for HTTP is redirected to HTTPS via the LiteSpeed Rewrite Engine. Currently there are no exceptions to this rule on the server except if you are already visiting HTTPS you obviously do not get redirected to HTTPS. So a description of the project along with the necessary syntax to exclude certain ports from your rewrite rule set are below.
LiteSpeed web server uses the same Rewrite engine that Apache uses so most of the information you will find on the Internet relates to Apache and not LiteSpeed. One of the projects I am working on redirects all web traffic that hits each virtual host from HTTP to HTTPS without exception. Recently it came up that we needed to do some API testing with a company that wanted to test on a development server to HTTP and not HTTPS. So I needed to figure out how to exclude a specific directory from our HTTPS Redirect Rule on one specific virtual host which turns out is really easy. Below I describe how to send all traffic except one directory to HTTPS via the LiteSpeed web admin.
