Description

This operator makes it possible to inspect the contents of HTTP variables (POST, GET or session variables). The "type" parameter can be used to specify which type of variable that should be extracted. The following options are available:

post (POST variable)
get (GET variable)
session (session variable)

The "check_existence" parameter can be set to TRUE or the string "hasVariable" in order to check if a directive is actually set. In this case, the operator will return either TRUE or FALSE. Note that using the "ezhttp_hasvariable" operator is a better option.
