Create a cache layer usable by all view engines

[mikey]

There needs to be a cache layer usable by all view engines. The cache layer should be able to cache whole HTML pages to save regeneration of pages if not necessary.

[mikey]

Changeset 1099 contains some initial thoughts for this.

[mikey]

Changeset 1121 added support for the website cache in the front controller.

[mikey]

A default website cache factory was added with changeset 1122.

[mikey]

Base implementation finished by adding various unit tests with changesets 1123, 1129 and 1130.

Still todo: reference implementation and documentation.

[mikey]

Reference implementation added with changeset 1136: net::stubbles::websites::memphis::stubMemphisProcessor now makes optionally use of the website cache.

Still todo: think about allowing the website cache to return a different stubResponse instance from its retrieve method. This would allow an fpassthru() on the cache files containing the complete site. Another todo: documentation.

[mikey]

Changeset 1140 introduced the possibility to deny caching of a page from a page element.

[mikey]

While a switch of the stubResponse instance itself would be possible it is not possible to use the fpassthru() function in the stubGzipWebsiteCache because the stubGzipWebsiteCache does only use a stubCacheContainer instance to put and get contents to and from the cache without knowing whether this is a file cache or a database cache or any other cache.

Therefore: implementation finished, requires documentation now.

[mikey]

Documentation created, see caching whole sites.
