URL validation

URL validation

We use an internal intranet site which has a short DNS name which Zoho CRM will not accept.  

When attempting to update the field it says "Please enter a valid URL".

The URL I am trying to set is  http://intranet/pm/

Our intranet is not currently setup with a full DNS name and given the amount of links using the shortname probably isn't a feasible change for us.
