Defined in packages/acs-core/request-processor-procs.tcl

Registers a filter that gets called during page serving. The filter should return one of

• filter_ok, meaning the page serving will continue;
• filter_break meaning the rest of the filters of this type will not be called;
• filter_return meaning the server will close the connection and end the request processing.

Switches:

-debug (defaults to "f") - If debug is set to "t", all invocations of the filter will be ns_logged.
-priority (defaults to "10000") - Priority is an integer; lower numbers indicate higher priority.
-critical (defaults to "f") - If a filter is not critical, page viewing will not abort if a filter fails.
-description (optional)

Parameters:

kind - Specify preauth, postauth or trace.
method - Use a method of "*" to register GET, POST, and HEAD filters.
