VIEWSTATE in ASP.NET Applications (sometimes not being changed)
Has anyone any experience of dealing with the __VIEWSTATE (and __EVENTVALIDATION) variables as used by ASP.NET applications?
I've dealt with them before in OATS but recently I've encountered an issue whereby on some steps, the __VIEWSTATE isn't being identified as dynamic. The majority of the steps do have a "SolveXPath: web.input.VIEWSTATE_xxx" where xxx is the unique identifier assigned by OpenScript. However certain other steps don't generate these.
I even have a custom correlation rule set up to attempt to catch these (but re-recording with that in place also doesn't generate a dynamic value).
I get the impression something is staring me in the face here (and I'm just not seeing it).
Any tricks/tips on VIEWSTATE would be appreciated.
