S
someone
Can anyone please help me with this problem. Thanks in advance.
This is a very simple site containing two pages listed below.
1. first.aspx
2. second.aspx
first.aspx contains only a textbox and a button.
second.aspx contains nothing, it is simply a blank page.
Whenever I click on the button to submit the textbox information from
first.aspx to second.aspx, the following error is displayed:
--------------------------
Validation of viewstate MAC failed. If this application is hosted by a Web
Farm or cluster, ensure that <machineKey> configuration specifies the same
validationKey and validation algorithm. AutoGenerate cannot be used in a
cluster.
-------------------------------
There's not much to it, but below is the code to first.aspx.
