There is a default option in Microsoft Internet Explorer 4 and later
versions that will cause a friendly HTTP error message to be displayed
when a Web site is blocked, rather than the response page generated by
the Webcache. You can turn this setting off by selecting Tools > Internet
Options > Advanced and unchecking Show friendly HTTP error messages.
The Proxy Auto Configuration (PAC) file is ignored by the Web
browser.
You must set the Web browser to read the PAC file for its settings; for
more information, see Proxy Auto Configuration (PAC) File Scripts on
page 50. 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.
