Padding is invalid and cannot be removed.

[MC]

Could someone please explain why I get 10-15 errors a day from my site
after the "googleBot" has visited?

To clarify, I should not use any postback functionality?

Hasn't the majority of the ASP.NET functionalitiy been provided by using
postbacks?

If I detected a bot what do I do to stop it serving invalid responses
the errors all seem to come from webResource and ScriptResource requests.
