This is an add-on plugin which lets Awebsome! Broswer Selector work on sites that employ caching.
If you use the Awebsome! Broswer Selector plugin AND a caching plugin (e.g. WP SuperCache), the wrong body classes will be served to your site visitors and could cause your site to render incorrectly. This plugin overcomes that limitation of ABS!
This plugin must be installed in conjunction with ABS 2.2 or higher.
