And it won't if 'http://webmail.domain' is the actual text, the ^ says "at the start of the line" (in other words, 'webmail\.' must start in character position 1). Choices: Remove the caret and accept the consequence that all references to "webmail\." will be changed or determine how to re-write (pardon the pun) the rule to narrow the scope to (such as) ^http://webmail\. (http:// at the beginning of the line). I'm not familiar with Apache regex implementation so I can't say that it will accept the construct I supplied, hopefully someone else can speak to that. ----- Original Message ----- From: "rgm" <rgm@xxxxxxxxxxxxxxx> To: "centos" <centos@xxxxxxxxxx> Sent: Thursday, February 23, 2017 9:43:59 AM Subject: Re: help with RewriteRule regexp I tried: RewriteRule ^webmail\.|/webmail https://%{SERVER_NAME}%{REQUEST_URI} [L,R] But that does not rewrite for http://webmail.domain On 02/22/2017 06:41 PM, Robert Moskowitz wrote: > Seems I left off one point in this message. > > This is to refine these rules in my Apache server. > > RewriteCond %{SERVER_PORT} !^443$ > RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R] > > I only want the rewrite if the URL includes webmail as I indicate below. > > I have found that now the RewriteCond is 'recommended' to be changed to: > > RewriteCond %{SERVER_PORT} !=443 > > But I have not found how to test for a string in the URL in the > RewriteRule. > > > On 02/22/2017 10:02 AM, Robert Moskowitz wrote: >> My regexp skills are somewhere infinitesimally close to zero.
