Handling Websites With Separate Mobile Versions

Caching may not work properly with websites that have separate Mobile versions which use a different skin than the main site uses.

In such cases, you can tell LSCache to cache a separate copy of the website's Mobile version so that the views are not mixed up.

If you are using the WordPress plugin, as of version 1.0.4, there is a configuration option that will add this rule automatically. Please see the LSCWP Cache Settings page for additional details.

Add the following to the .htaccess file (these are just some examples only and you may have your own rules):

RewriteCond %{HTTP_USER_AGENT} "android|avantgo|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge\ |maemo|midp|mmp|opera\ m(ob|in)i|palm(\ os)?|phone|p(ixi|re)\/|plucker|pocket|psp|symbian|treo|up\.(browser|link)|vodafone|wap|windows\ (ce|phone)|xda|xiino" [NC]
RewriteRule .* - [E=Cache-Control:vary=ismobile]


RewriteCond %{HTTP_USER_AGENT} "iPhone|iPod|BlackBerry|Palm|Googlebot-Mobile|Mobile|mobile|mobi|Windows Mobile|Safari Mobile|Android|Opera Mini" [NC]
RewriteRule .* - [E=Cache-Control:vary=ismobile]

This feature is supported as of LSWS version 5.0.7.

Important: Your rewrite rules must exactly match your backend's mobile detection. If these do not match, you may run into the issue where your rewrite rules think that a device is mobile while the backend does not and visa-versa. This can cause, for example, the desktop version of a page to be cached and flagged as the mobile version which will then be wrongly served to all mobile viewers.

For example, for Magento LiteMage users, once you set the above in .htaccess, you have to set the exact same expression in the Magento administrative area: Navigate to System > Configuration > Design > Themes > Add Exceptions and place the expression used in .htaccess here. If it's not exact, it may not return the right contents.
