Using automatic configuration script to discover a proxy server

Alek Davis

12/26/2002 8:45:00 PM

Hello,

Is it possible to allow a Web service to discover a proxy server when the
default IE LAN configuration is set to "use automatic configuration script"?

The problem I have now is that a client behind the firewall, who "use[s]
automatic configuration script" option, cannot call a Web service outside of
the firewall without having to manually change IE LAN settings (i.e.
disabling "Use automatic configuration script" option and defining proxy
server address and port manually). Requiring users to perform this manual
step (and revert back to the original settings after calling a Web service)
sounds like a hassle, so I am looking for alternatives. Is it possible to
let a Web service proxy class to discover proxy settings automatically? If
not, can it be done the way IE does it, i.e. discover proxy info from the
configuration script and set it programmatically?

Any ideas are greatly appreciated. Thank you in advance.

See the following MSDN articles. You can programatically
handle the proxy server or you can use the machine.config
configurations.

Thank you for the suggestion,

These are good articles, but this is not exactly what I am looking for.
First, I do not want to require the end users to make any changes to their
config files. Second, the KB articles show how to set up global proxy
settings, when you already know the name (port) of the proxy server. What I
am trying to find out is: how can a program find the name and port of the
proxy server if the system uses automatic proxy discovery script (i.e. the
way IE does), so that the Web service client can set proxy info before
making a call without user interaction or changes to config file. The
information is already there, and since IE can figure it out, there must be
a way to do the same thing programmatically.

Check these:

http://msdn.microsoft.com/library/en-us/winhttp/http/winhttp_autop...

http://msdn.microsoft.com/library/en-us/wininet/wininet/autoproxy_...
_wininet.asp

Requires some work to use them from .NET though.
