iRule https POST parameter catch and data verification

Hello DevCentral community,

I have a big question for you regarding an iRule implementation, i'll try to explain it below :

My Virtual Server receives HTTP POST DATA, i need to catch from the POST DATA some parameters like user,pwd,token, regarding this, Can i store them in a temporary table? i must verify the token validity from return traffic of the authentication process ( can i capture it and store it in a temporary table ? in order to re-use it in the evaluation process ) In order to avoid a generation of a specific request that evaluate the token validity querying the auth server.

I hope i was clear enough,

Thanks in advance,

Best Regards,

M.
