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.
