I want to make a fake POSTBACK request to aspx webpage which is hosted in IIS 7.5 server with .NET Framework 4.
When i clicked a button seemingly the login button of the page.It just posts the data with
__EVENTVALIDATION and __VIEWSTATE and myButtonId with value Login(Caption of my button).
After hitting the Login button the webpage sents back the result such as Incorrect username or password error message inside tag.
But i want this login button operation done within a single post request.
What i have tried so far?
I know that __EVENTVALIDATION parameter contains the validation of controls or is there any tampering occured in an encrypted way this is checked from the server.
Like that i have passed the __EVENTVALIDATION and __VIEWSTATE(the both key values are obtained from the previous request that had been made to the server) and username and password and the buttonId to the server.
But all fails it just loads as it is the first request. The server can't identify it as a POSTBACK request.
What to do?.Iam just cracking my heads for days.
Is there any techi over here to solve my problem? And one request dont make it as a duplicate.Because from all previous stackoverflow questions i did'nt get an acceptable answer.So what iam here posting this...
