Because my custom plugin calls external application server to check some
conditions
to authorize

At this moment I will make two identical calls to server , so that second
will be discarded, if I handle both OPEN and DESCRIBE

At the bottom of line I've to check if url contains word "protected" that
means user must enter credentials and for this reason I wrote a Custom Digest
Authontication Plugin.

Once user is authenticated there are other conditions to check, like that
max number of streming allowed ,for a determinated publisher of media
content, has not been reached and that's why I've to call an application
server

All these controls were done at Authorization Level at OPEN until when HTTP
problem has not been raised

I could check url at DESCRIBE and CALL Server to OPEN but anyway it works
only if DESCRIBE event is always raised........

Any suggestions ??????
