APM variable assign examples

Hi,

Thanks for info. I am trying to create branch expresion to change flow based on Host in request. Tried to use such code:

expr { [mcget {session.server.network.name}] == "form-ntlm.mbank.org" }

but it fails, always fallback branch is used. Using Message Box before Branch test I can see correct value in this var. If I use iRule to assign host header value to some custom session var and then perform the same expression selection is working correctly.

Is session.server.network.name some special kind of session var that can't be used for branch test?
