custom http 400 error page

HI ,

I want to change the default error message for http 400 error with my error message .

I have made changes in
httpd.conf but the same is not reflection in the response pages .

i have made 2 changes to httpd.conf

  1. uncommented ErrorDocument 400 /error/HTTP_BAD_REQUEST.html.var
  2. changed ErrorDocument 400 ":AGPRSOKB; 400 error " to display :AGPRSOKB; as the error message as the message when http 400 takes place .

I restarted the apache after making the changes.

but i am still getting the same html error .
