Chapitre 4. The cache system

 

Cached bits

In addition to caching the full pages, there is another way to ease processing. />

As the files are included by PHP and no accessed through theweb server, this directory may be anywhere on the filesystem. So the configuration parameter $this->cachedir is an absolute path while $this->htmldir is a path relative to htdocs.

If this parameter is left empty, the cache is turned off.

You need to make sure Apache may write in this directory, as you did with $this->htmldir.
