Validation of viewstate MAC failed.

[=?Utf-8?B?Sm9oYW4gQWxtYmxhZA==?=]

I have a major problem with my app when I´m using dynamicly added controls
and URL rewriting.
When I do a postback I get this error all the time:
Validation of viewstate MAC failed.

Any solutions out there?

There was no way for you to know it (except maybe by browsing through some
of the previous questions in this newsgroup before posting yours - always a
recommended practice) , but this is a classic (COM-based) asp newsgroup.
ASP.Net bears very little resemblance to classic ASP so, while you may be
lucky enough to find a dotnet-knowledgeable person here who can answer your
question, you can eliminate the luck factor by posting your question to a
group where those dotnet-knowledgeable people hang out. I suggest
microsoft.publi c.dotnet.framew ork.aspnet or the forums at www.asp.net.
