SetInputFilter
SetInputFilter filter[;filter...] Server config, virtual host, directory, .htaccess
The SetInputFilter
directive sets the filter or
filters that will process client requests and POST input when they
are received by the server. This is in addition to any filters
defined elsewhere, including the AddInputFilter
directive.
If more than one filter is specified, they must be separated by semicolons in the order in which they should process the content.
