: Using mod_rewrite to set cookie and modify domain name I have two editions of a website. The mobile and desktop version. All desktop sections of the website have normal urls and mobile sections

I have two editions of a website. The mobile and desktop version. All desktop sections of the website have normal urls and mobile sections have subdomain urls suffixed with the word mobile.

Example:

Main desktop site could be: core.website.com/ Mobile version of the same site could be: core-mobile.website.com/
Main promotional site could be: promo.website.com/ Mobile version of the same site could be: promo-mobile.website.com/

I want to try to achieve the redirections with mod_rewrite. Currently, I want to include the following lines in htaccess to detect mobile devices:

RewriteCond %{HTTP_USER_AGENT} (android|bbd+|meego).+mobile|avantgo|bada/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge |maemo|midp|mmp|mobile.+firefox|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)/|plucker|pocket|psp|series(4|6)0|symbian|treo|up.(browser|link)|vodafone|wap|windows ce|xda|xiino [NC,OR]

But the real core of the problem lies here:

RewriteCond %{HTTP_COOKIE} !DMOB=1
RewriteCond %{SERVER_NAME} ^(.+)^[(-mobile)]$ [NC]
RewriteRule ^(.*)$ %1-mobile/ [R=301,NC,L,CO=DMOB:1:.website.com:144000:/]


What I'm trying to accomplish here is the following:

When user visits a website without the -mobile sub-domain suffix, using a mobile device (as detected by the first two long RewriteRule lines) the system checks to see if the cookie named DMOB has a value of 1. If it does then nothing special happens and the requested site loads.

If however, DMOB is not set to 1 and a mobile device IS used, then the mobile sub-domain suffix must be added to the subdomain and then DMOB will be set to 1 starting with the next request and the url will be redirected over to the same thing plus the word -mobile appended to the subdomain name.

I tested it with curl using 1 and 0 for DMOB cookie values and I even tested it without the long mod_rewrite lines.

I think it has something to do with this line:

RewriteCond %{SERVER_NAME} ^(.+)^[(-mobile)]$ [NC]


But at the same time, I think that ^ means negate (or should I use a ! ?)
