This class can be used to wrap the service of the requests to all pages of a site using a single PHP script.
It takes as argument an array that defines the mapping patterns of request URI to wrapper scripts that should be executed within a safe container when the given URI patterns are matched.
If a wrapper script sets an error variable, the generates a 403 forbidden access HTTP error page.
Request URIs that do not match any pattern make the class generate a 404 not found HTTP error page.
The content outputted by the wrapper script is buffered by the class. It can optionally be served in a compressed format.
