Allow IE running in parallels to access a locally hosted app

Yes it should work out of the box, because Windows running on
Parallels and your Mac OS X should have two different IP addresses.
Just goto the particular ip address from within IE.

If you need to know your IP address on the Mac side you can run '/
sbin/ifconfig' from a Terminal session. They're might be an easier
way to figure out the IP address, but this works.
