httpproxy authentication & agent simulation

[runrev at animabit.de]

Hello Mark Smith

thank you very much for your tipp using HTTPHeaders for implementing another User-Agent! 

In the archives I found with the help of Mark Schonewille

From: Dave Cragg <dcragg at ...>
Subject: Re: HTTPProxy - authenticated proxy servers supported?
Date: 2003-08-21 09:33:29 

with information how to use proxy authentication. 

The solution in both cases uses HTTPHeaders. I try to set the HTTPHeaders to a multiline string
"User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)"
& cr &
<put proxyusername into tID
put proxypassword into tPass
put base64Encode(tID & ":" & tPass) into tString
set the httpHeaders to "Proxy-Authorization:" && tString>
& other Headerinformation 

Perhaps I can avoid the shell(Perl-journey) and stay in runrev even in this case. Thank you.

Nice day,

Franz

Franz, you can spoof the user-agent using another httpHeader:

set the httpHeaders to "User-Agent: Mozilla/4.0 (compatible; MSIE  
6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)" --  
or somesuch, this will override the default user-agent.

I'm pretty sure you can do http authentication with a header too,  
using the "WWW-Authenticate:" header, but I'm not sure exactly what  
form it takes.

Hope this helps,

Mark
