Question

I have a form on the page that is populated with POST parameters. Suppose if I send an ID request via POST and all the fields are populated based on this ID from the database.

When I refresh the page, it asks me for permission, as shown below

and this operation works fine in all browsers except IE. when I click Retry in IE9 then I get

Unacceptably!
The corresponding representation of the requested resource cannot be found on this server. This error was created by Mod_Security.

I read somewhere to solve this problem as below

 <IfModule mod_security.c> # Turn off mod_security filtering. SMF is a big boy, it does not need its hands held. SecFilterEngine Off # The below probably isn't needed, but better safe than sorry. SecFilterScanPOST Off </IfModule> 

But that doesn't work either.
