I am using JMeter to load test ASP.net application. I am able to successfully record login functionality & further workflow,however when I try to playback the same recorded script next time or next day,the login always fails. My test plan has following elements --
HTTPRequestDefaults
HTTPCookieManager
Thread group
Recording controller
After login GET request, I have extracted __VIEWSTATE & __EVENTVALIDATION parameters using regular expression extractor & passed it on to subsequent request. Can someone help here ?
