When the form is submit, the __viewstate and __viewstategenerator are post to another page, and the Verification view state MAC fails.

Error message: Verify view state MAC failed. If this application is hosted by a network farm or cluster, make sure that the configuration specifies the same validationkey and validation algorithms. You cannot use AutoGenerate in a cluster.

F_app_cux_pro.aspx Page Original code:

This.form1.action = "F_add_app_cux_pro.aspx?" Cuxid= "+$ (" #CuxId "). Val () +" "; This.form1.submit ();

That is, from a page submitted to page B, form submit when the page a __viewstate and __viewstategenerator together post to the B page, the Verification view state MAC failed.
