Cache Control

Capitan checks various data points to establish wether to deliver locally cached content or to force content to be loaded from the server.

Any time that server resources are loaded a record of the date/time is recorded as a cache identifier.

On subsequent visits, if any Capitan content or templates have been modified since the recorded date/time then content will be force to load from the server again. Otherwise locally cached content will be delivered.

To prevent stubborn CSS cacheing, you'll notice a php varaible called $cachevar is used to attach a string to linked CSS resource. The value of this string is the same date/time identifier used for the HTML cache header.

Developers can use the URL string capdev=your_dev_code to force refresh all content
