Well, they may have been set up by an external consultant, but that doesn't
mean they /cannot/ be changed. :-)
However, we'll work with what you have. The good news is that the server has
been configured to support both.j
It appears to me (though I've not actually tested this as I do not have a
proxy server deployed), is to set the port-specific proxy configurations
using Internet Explorer, and then import those configurations into the
proxycfg.exe settings using 'proxycfg -u'. There is also a syntax for
setting them directly, but it's tedious and complex, and it seems that
importing the settings from IE is much simpler and more reliable.
Open Internet Explorer, select Tools > Internet Options, or open Control
Panel, and select Internet Options
From Internet Options, select the Connections tab, and click on the LAN
Select "Use a proxy server for your LAN"
Add the IP Address of your proxy server, and port number for HTTP
connectrions (8080 as you've noted here).
Select "Bypass proxy server for local addresses"
Click on the Advanced button
On the Proxy Settings dialog box, uncheck the option "Use the same proxy
server for all protocols"
Then, in the port column for "Secure", change the port number to 8443.
If you also support FTP or Gopher proxies, you can assign those port
numbers, or to disable the proxies entirely, delete the values configured.
Click on OK and close out of Internet Options.
Open a Command Prompt window and execute 'proxycfg.exe -u'
Then execute 'proxycfg' to confirm your settings are in place, and restest
