where 
nnn
is a decimal number between 0 and 255. An example IP 
address is ‘192.168.1.253’. The port number on which the Webcache

In Netscape, you can enter a shortened PAC address such as 
webcache:8082 and Netscape successfully configures itself using the PAC 
file. In Internet Explorer, however, this address is not recognized and you 
are not warned that the PAC file is being ignored. You must include 
"http://" at the start of the URL i.e. http://webcache:8082.
