Hi all
i have deployed my website on a particular server. i
have some limitations in using viewstate and session variables.
those
pages in which i have used ViewState variables (for storing some
information), i user accesses that page and does not do any activity for
5 minutes and if after 5 minutes he does any kind of activity (click on
Link or button etc) then he receives following error:
"Validation
of viewstate MAC failed. If this application is hosted by a
Web Farm or cluster, ensure that configuration specifies the same
validationKey and validation algorithm. AutoGenerate cannot be used in a
cluster."
how i can avoid above error?
another
problem is with session. My session expires just after 2-3 minutes.
What should i do for maintaining session for long time? i can not use
cookies, as if user has disabled the cookies then my website will not
work...
...
Go to the complete details ...
