Error 400 - Bad Request after enabling custom Subdomain/Domain names

PROBLEM
--------

After enabling Custom Domain on your portal you receive the following error 
whenever you attempt to access it via new address:


FireFox might display:

   Error 400 - Bad Request


Internet Explorer might display:

   The page cannot be found
   
   The page you are looking for might have been removed, 
   had its name changed, or is temporarily unavailable.
   
   HTTP 400 - Bad Request
   Internet Explorer 


SOLUTION
---------

Please make sure to first create DNS CNAME Record pointing your Custom Domain 
to p010.hashjoin.com example:

   subdomain.domain.com -> p010.hashjoin.com
OR
   www.domain.com -> p010.hashjoin.com

Your DNS server might take few hours for the change to take affect until then 
you will continue to receive such errors.  These errors are raised by your ISP 
-- not HASHJOIN server.
