Please Note: This wiki is valid for v2.9.x and below of the LiteSpeed Cache Plugin for WordPress. If you are using v3.0 or above, please see the new documentation.

LiteSpeed Cache can be configured to save multiple variations of the same page, based on the value of a cookie in the user's browser.

Example: Assume you have a WooCommerce site with a “woocommerce_products_per_page” cookie. For some users, the value will be 10. For others it will be 100. And still others may not have a value of 200. These three scenarios require three different views.

There are two ways to accomplish this:

The more efficient option is to find a JavaScript-based solution. A JavaScript plugin would only need to store one copy of the page and would build the display based on the existence of the cookie.

If a rewrite rule-based answer is preferred, the site can be configured to vary on the cookie by adding the following rule to your site's .htaccess file:

<IfModule LiteSpeed>
CacheLookup on
RewriteRule .* - [E=Cache-Vary:woocommerce_products_per_page]
</IfModule>

When a user visit your WooCommerce site, the woocommerce_products_per_page=xxxxxxcookie will be created. Using the rewrite rule above, the cache will vary on that cookie. This means the cache will store multiple copies: one for every value of the cookie that requests the page.
