Making XP Pro. SP2's IIS as a proxy server?

[ma_khan]

Phillip,

What you "define" and "call" proxy depends a lot upon your PAC script so I
wouldnt know much about that. However, coming to the second part of your
question on downloading the proxy settings on client computers (example
foo.pac) you will need to add the following Mime-Type in your IIS server:

extension: .pac
mime-type: application/x-ns-proxy-autoconfig

Hope this helps.

Hello.
Is it possible to can make XP Pro. SP2's IIS (installed/added from its XP
CD) act like a proxy server for Web transfers to client PCs on the LAN? I
want client Windows PCs connect to the proxy server to access the
Internet.
I am also trying to set up client PCs to download *.pac (proxy
automatic configuration) scripts, from IIS server, to web browsers (e.g.,
IE6) to transfers datas via IIS proxy server for external Web sites (e.g.,
Google.com).
I was able to make a PAC script to work, but going to Web sites like
cnn.com show "Under construction..." error. :( I guess that means my
client PC is going to the IIS server, but not going outside like a proxy
(couldn't find a way to enable this in IIS).
I did manage to make this proxy server setup to work with Apache v2.2 on
another machine. I am still new at this area (not an administrator guy),
so I might be missing something.
Thank you in advance. :)

Well, I also did it manually (enter values; no script) but that didn't
work either. Here's a sample script:

function FindProxyForURL(url,host)
{ if(isPlainHostName(host)||
isInNet(host,"192.168.0.0","255.255.0.0")) return "DIRECT";
else return "PROXY 10.147.27.242:8080";
}

Yep, I have that already. Here's a screen shot:
Loading Image... ... It works.
Just can't get the proxy to work via IIS to the Internet.

Hi Philip,

I am not into proxy so really wouldn't know much, as far as I can tell you
from IIS side if you have the MIME type set then you are good to go... rest
depends on your PAC script... However, I have seen people implement proxy on
the basis of ASP and an ISAPI filter. Following is a download available at
iis.net... Hope this helps...

Thanks. I will check it out. I hope I don't have to program/code to make
it work since that is not my strong area. :)

Hmm, I can't seem to get the proxy sample path as shown in step #3 in
http://www.iisproxy.net/setup.html ... I tried to use the live samples
in http://www.iisproxy.net/live-samples.html but it said "I'm sorry,
live IIS proxy samples was removed, because they were working :-(.". I
tried without changing the "NotFoundScript=/redesign.asp?" line in
iisproxy.ini in the set Home Directory, but I am getting the same
results. Maybe I did it wrong. :(

Also, I tried _proxy.asp file (copied to IIS' home directory path
included in http://www.iisproxy.net/iisproxy.zip). That did not work as
well. :(

Is it possible to can make XP Pro. SP2's IIS (installed/added from its
XP CD) act like a proxy server for Web transfers to client PCs on the
LAN? I want client Windows PCs connect to the proxy server to access the
Internet.

(To the best of my knowledge.)

No it is not possible to get (stock) IIS from Microsoft to behave as a
proxy like Apache's mod_proxy. IIS simply does not have this
functionality. That being said I have heard of people writing a script
that behaves like a proxy.

I am also trying to set up client PCs to download *.pac (proxy
automatic configuration) scripts, from IIS server, to web browsers
(e.g., IE6) to transfers datas via IIS proxy server for external Web
sites (e.g., Google.com).

You have a couple of different options. You can configure DHCP to use a
vendor specific DHCP option that direct IE (and possibly others) to pull
a Proxy Auto Config (PAC) / Web Proxy Auto Discovery (WPAD) file from a
specific URL. You can also configure IE (and possibly others) to look
for a specific URL (usually "http://wpad.domain.tld/wpad.dat") to pull
the PAC / WPAD file from.

I have successfully set up the DHCP option to specify the URL to pull
the PAC / WPAD file from for multiple clients. I generally set the DHCP
option to the same URL that would be used by the WPAD option to make
things simpler and more compatible with as many things as possible. (I
believe non IE browsers like WPAD better.)

Word to the wise, Microsoft DNS server are by default configured to not
serve up a "wpad.<what ever>" resource record. You have to run a
command to have the DNS server serve up what Microsoft considers
""dangerous resource records. I believe the intent is to help thwart
hijacking of browsers by configuring them to access the wrong proxy.

I was able to make a PAC script to work, but going to Web sites like
cnn.com show "Under construction..." error. :( I guess that means my
client PC is going to the IIS server, but not going outside like a proxy
(couldn't find a way to enable this in IIS).

Most likely.

I did manage to make this proxy server setup to work with Apache v2.2 on
another machine. I am still new at this area (not an administrator guy),
so I might be missing something.

See my comment above about IIS verses Apache's mod_proxy.

Thank you in advance. :)
