Hi ujwols
Thank you for your answer.
So for example, if I want get the [HTTP_SM_SERVERSESSIONID]'s value by the name [SM_SID]
1.Click [Response]
2.Select Attribute type [Web Agent-HTTP-Header-Variable]
3.Select Attribute kind [User Attribute]
4.Type Variable name [SM_SID]
5.Type Attribute name [HTTP_SM_SERVERSESSIONID]
Right?
