I am using Delphi Professional 6.0 pack 2 with ICS. I'm not sure what version
of ICS I am using since I don't see the version number in the README. However,
I checked HttPProt.pas and the final comment reads:
"Oct 15, 2004 V1.71 lotauro.mauri...@dnet.it enhanced basic and NTLM
authentifications methods. Event OnNTLMAuthStep has been
removed."
I am trying to access a server that requires Basic Authentication. I can
access the server without problem using FireFox. When I try it with THttpCli
it hangs on the second attempt after it sends the request with the proper
Authentication header line. I matched the Header data up as best as I could
between what FireFox is sending and with what THttpCli sends during a Post
attempt. I captured the Header and Data send and receive events and the
Headers appear to be identical where it counts (Authorization, Content-Type,
Accept, etc.). Note, I configured the Headers using the THttpCli properties,
not by modifying the data in the OnCommand event (UserName, Password, Accept,
ContentTypePost, etc.). I logged the transaction and I can see that THttpCli
handles the initial 401 error, closes and reopens the connection, and makes the
second attempt with the correct Authorization line in the Header data. I
matched the encoded UserName/Password to the FireFox
session and they are identical. However, after the request is sent with the
Authorization data, THttpCli just hangs waiting for something until I Abort the
connection.
Does anyone know what is going wrong here or what I can try to debug it? I
have included the log I captured during the THttpCli Post session. I have
removed the encoded UserName/Password and added comments where I thought it
might help.
Thanks,
Robert
