Assumption: There is a site kulshresht.com and it supports both version, Desktop and mobile site but with different code base on each of them.
Desktop version --> www.kulshresht.com
Mobile site --> m.kulshresht.com
The below rule redirect visitors from different mobile devices to mobile site.We have also added a support for a cookie, so that mobile users can still opt to visit the full site, in case they don't like mobile site.
The first block checks to see if it is a mobile device and there is neither a cookie nor a url parameter set. If those conditions are met, redirect the visitor to the mobile site. The second block looks to see if the url parameter is set and there is no cookie. If those conditions are met, set a cookie for the user.
In practice, this will automatically redirect mobile users to a mobile site. On the mobile site, add a link going to www.kulshresht.com?fullbrowser=1. When the visitor uses that link, they will get back to the original site, a cookie will be set, and they can now bypass the redirect while the cookie is still valid. The point is to redirect mobile visitors, but not permanently if they still want to visit the full version of the site.
Download Apache config from http://detectmobilebrowsers.com/ and we can use that for detecting mobile in mod rewrite.
