I have setup and configured Web transaction monitoring which has been working well, however, when a new session is required (for example do not monitor for a while), the monitors fail as sessionstate is no longer valid.
Reviewing the logs, an "Invalid viewstate." error is been raised.
Looking at the details of the transaction recorder includes "&__VIEWSTATE=xxxxxx" into the post of the page. This is recorded from the initial user recording, and does not get changed. I have been trying to use variables try capture the previous pages VIEWSTATE, in an attempt to make the viewstate value change with each monitoring session. Unfortunately I have not been able to get the working thus far.
Viewstate / sessions are pretty common place, so I am asumming their is an easy way to achive this.
