how to handle the error if wrong file extension has given RRS feed

  • Question

  • Dear all,


           Tell me how to handle the error when a wrong file extension has given,

    If  i am giving wrong page name then it is easily handled by the customerror page

    But if i am giving wrong file extension(like default.aspxhfg) then it could not be handled,

     because i know that each file handled by IIS as per their extensions,if the extension is known by the IIS then it handles that request by using the handler or by itself(in case static file like .jpg,.png etc), but if it is not known by IIS then it is directly showing the 404.0 type error, so please tell me how to handle this kind of error.

    so please guide me how to solve this
