Aristotle, In order to fix the 20-min timeout issue, I went for your first option below and it seemed to work for a while. Now when I try to submit a form that was opened before application recycled, I get this... "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." Steps: form opened, app recycled, form submitted, error! I would like to attempt your second option that you mentioned below. I read through the article you posted but they ask for modification of machine.config.How do I implement that on DiscountASP.Net-hostedservers, knowing that I cannot modify your machine.config? Jimmy ------------------------------------------------------------------------------ Posted 11/9/2006 12:30 PM (GMT -8) This is a problem with the forms authentication cookie. Data in the cookies are encrypted using a machineKey that gets generated randomly every time a web process gets recycled. Cookies that were created using the old machineKey will no longer be valid. We recycle web processes that have been idle (no hits whatsoever) for 20 minutes regardless of session timeout. To resolve this, you have a couple of options: 1. Set the protection attribute in the forms element to "None". 2. If you want to keep the protection enabled, you must create your own machineKey so that it's constant.

You could set the machine key in your web.config. Also see: (key generator) http://www.aspnetresources.com/tools/keycreator.aspx Post Edited By Moderator (Joel Thoms) : 11/13/2006 11:20:12 PM GMT
You can also set the enableViewStateMac property to False in the page element of the web.config. See http://msdn2.microsoft.com/en-us/library/950xf363.aspx But the best solution is to generate your own machineKey. It's used by ASP.NET in many things that you'll find that you'll be modifying so many parts of your application just to work around it.
