There are some meta characters at the cookie header which i need to allow ? i dnt want to change in global character set but just at the cookie . is there a best way to do via irule ? or is there any other way ?
any one has a solution ?
Sorry Draco, unfortunately "Security ›› Application Security : Headers : Character Set" is the only character enforcement available for HTTP headers and as you mentioned, this is a global set and not per header.
I would recommend that you open a support case so a Request For Enhancement can be raised.
