Pages caching
The caches of pages exploit the new functionality of PHP 4: the "output buffering ", which allows to redirect the output of a script to a screen, a file, etc.
These solutions are generally composed of a single script PHP which it is necessary to include in scripts that have to be cached. Technically, they collect the outputs generated by scripts in order to store them in a file or a database.
This mechanism is very effective for the home pages of websites which evolve little.
