Apache : How to use a mod_rewrite rule to redirect url with empty query string parameters

 We will see how to  use mod_rewrite to reditect url in a configured virtual host

This example is based on a url with incoming query string empty. The trick is to use a RewriteCond to match the empty query string portion of the URL, and a regular RewriteRule to match the path.

<virtualhost>

    ServerAdmin awesome@test.com
    DocumentRoot C:\test
    ServerName test.com

     <directory test="">
       Order allow,deny
       Allow from all
       AllowOverride All
    </directory>
    
    RewriteEngine On
    RewriteCond %{REQUEST_URI}  ^/web/guest/myurl/$
    RewriteCond %{QUERY_STRING} ^$
    RewriteRule ^(.*)$ http://www.mynewdomain.com/ [R=301,L]

</virtualhost>    

As result the url

http://www.mycurrentsite.com/web/guest/myurl/ will be redirect to http://www.mynewdomain.com/

the url

http://www.mycurrentsite.com/web/guest/myurl/?id=576576 will not be redirect.
