I have been asked to allow the web server to be able to browse to its

Why isn't it? Okay, some firewalls are broken with this respect and
won't allow access from and back to via the same physical interface.

  

With out putting an entry in the host file of the server to resolve
the web url to the local host is there anything that could be done on
the firewall? 


Give the server his own IP address locally as secondary IP on the
primary interface, maybe even with a /32 netmask?
