<p>My Site's error log is filled with these errors:-</p>

<p>This is an invalid script resource request.
Invalid viewstate.
Invalid character in a Base-64 string.
Invalid length for a Base-64 char array.</p>

<p>All these errors are appearing at least 100 times a day.</p>

<p>After doing some RnD on internet i have done following things:-</p>

<p>1- define machine key in my web config.
2- created robots.txt file and add ScriptResource.axd file in that.</p>
