With Appcache you can select specific pages (or even the full site), which will be preloaded for the visitor on the first view using browser’s Application Cache. It can dramatically speed up navigation on your site. You can configure Appcache separately for desktop and mobile

Enable Appcache for Desktop
You can enable Appcache for desktop devices.

Appcache Mode
Appcache mode can be “Full site” or “Specific pages”. If you select Full site you can specify exceptions, if you select specific pages you can select the pages (or page rules) which should be preloaded and cached with Appcache

Desktop Max Size
Appcache maximum full size on desktop devices. That is the size that the visitor’s browser will download and cache. Default is 100Mb for desktop and 5Mb for mobile devices.

Exclude Pages
You can select pages which shouldn’t be cached with Appcache. This option will be available if you select Full site as Appcache Mode.

Exclude Strings
You can exclude pages from Appcache if one of these strings is found in the URL. This option will be available if you select Full site as Appcache Mode.

Include Pages
You can select pages which should be cached with Appcache. This option will be available if you select Specific pages as Appcache Mode.

Include Strings
Cache pages with Appcache only if one of these strings is found in the URL. This option will be available if you select Specific pages as Appcache Mode.

Enable Appcache for Mobile
You can enable Appcache separately for mobile devices. All other options are the same as for desktop

If you would like to increase Appcache size for mobile devices to more than 5Mb, please note that the browser may will prompt the user for permission to use storage. This limit is undocumented, and highly variable. It is recommended to use the default 5Mb limit for mobile devices.
