Propably I'm the only one interested in this :-)
But anyway, I've checked it out, it's really very easy to do this for
basic authentication. You only have to add one more HTTP-header line:
"Proxy-Authorization Basic YWRtaW46Zm9v"
where YWRtaW46Zm9v is a base64 encoded string of <username:password>
("admin:foo" in this case), and you have to use a full URL in the
GET-line
(like "GET http://macromedia.com/robots.txt";)
If you specify this additional header right away from the beginning,
there is no need for an "interactive authentication", you get through
the proxy immediately (tested with Squid 2.5 on win xp)
So, Tim, if your proxy server uses basic authentication only (which it
propably doesn't), there is no need to buy a third party xtra.

thanks cole, laurent for your replies.
laurent, what part of the process that you described do you think
wouldn't be possible to implement with multiuser lingo? If I
understood you correctly, this doesn't sound very difficult, as long
as the whole
communication is text based, not binary (what seems to be the case for
basic authentication). It's no problem to implement other text-based
protocols like SMTP, POP, HTTP etc. with multiuser lingo/xtra.
cheers,

I don't think you can. The way the authentication is handled,
independantly from the authentication scheme is, that way:
- prerequisite : any access to an http resource throug a proxy that
require authentication has to be done with the "Keep connection
alive" flag set on.
- The client issues first a GET (going through the proxy server) set
the
proxy info (IP/port) but no user or password.
- The the HTTP server replies with a 407 error code (indicating that
the
proxy requires authentication) and includes in the header the
authentication scheme expected (basic, NTLM, Kerberos, ...)
- The client then starts to handle the authentication protocol and
once
access granted, re-issues the GET
I don't think Multiuser could handle this scheme. It would have been
a different story if you have pass the user name/password in the
initial request.

I wonder if (depending on the authorization scheme?) you
could use the multiuser xtra to authentificate at a http
proxy server...?
Does anyone know more about this?

Thanks for that Valentin, Duck,
I actually stumbled across the proxyserver function after
my post, But
looks like a client requires user\pass authentication on the proxy
server as well, so may need the xtra Duck suggested,
although I also
found "UntimateNetXtra" as well which seems to be a better deal for
the price.
Shame that the proxyserver function only seems to be "half
implemented"
I can't think of any good reasons why they wouldn't build
in a method
for sending user pass parameters.
Cheers guys

hi tim,
look up
proxyServer(serverType, "ipAddress", portNum) in the help.
you can either get the proxy server's IP from the registry (pc,
require's some (free) xtra; on the mac there is propably
some comand
to use with shell xtra), or let the user specify it manually.

Hi,
Anyone know how I can use things like getNettext when the computer
uses a proxy server to access the internet.
Do I need to use a 3rd party xtra like UltimateNetXtra, or
is there a
way with just normal director lingo (MX 04)
Thanks
Tim
