Hi Arno, Ok, let me explain: due to stupid BCB linker errors,I had to place the function below in a pascal unit for calling the function you said: function THttpMTConnection.GenerateDigestChallenge : String; begin Result := AuthDigestGenerateChallenge( FServer.FAuthDigestMethod, FServer.FAuthDigestServerSecret, FAuthRealm, '', FAuthDigestStale, FAuthDigestServerNonce, FAuthDigestServerOpaque); end; And it still does not work.

Re: [twsocket] Need help with HTTP/1.1 digest auth for forward proxy
I forgot to say: I also changed the parser for Authorization: request
header to Proxy-Authorization: and that parser works well. But the problem
remains.

Hello,
Even though the code works for reverse proxy, it does not when I make it a
part of IE/FF chain as forward proxy! In Answer401, I wrote:
String AuthString = auth;
String staleString = String((FAuthDigestStale lastCommand !=
cproxyCommandPOST) ? , stale=\true\ : );
String prefix = (Owner-Tag 0 ? https://; : http://;);
String URI = FPath;
headerHead += Proxy-Authenticate: Digest + // I only changed this line
from rproxy to forward proxy
GenerateDigestChallenge() +
, domain=\ + prefix + FAuthRealm + : + serverPort + \ +
, uri=\ + URI + \ +
//, algorithm=\MD5\ +
staleString + \r\n;
and in ConnectionDataAvailable, before the processRequest ( I have my
descendent of THttpServer by the way):
else if(!FRequestAuthorization.SubString(1, 6).AnsiCompareIC(Digest))
{
FAuthDigestBody = ;
FAuthenticated = AuthDigestGetParams();
if(FAuthenticated)
{
username = FAuthUserName; // NO matter even the username is correct,
never reaches here!
String bufferPassword = serverPermissions-getUserPassword(username);
I am not sure how to debug this as the data is encrypted. I know we were
the pioneers in digest coding that we had had coded in Bulgaria and then
Francois fixed it. But now it's a different story--forward proxy. Any idea
what's wrong? The forward proxy units were copied from reverse proxy ones
and then altered so the variable's reset points are exactly the same that
has been working in rproxy. I hope you can help.
Thanks in advance,
SZ

Re: [twsocket] Need help with HTTP
The error I get is it sometimes shuts down before all the
data is actually pumped.
Your code fragment is difficult to understand. There are to much noise
because of features in your program. You'd better build a simplified code.
Anyway, if this can help you, I remind you that OnDataSrnt event doesn't
mean the data has been sent out to the remote site but that TWSocket has
emptied his buffer to winsock own buffer. Winsock has still to send data and
for for ack. There is no way to know that winsock has completely sent
everything out and received corresponding ACK, except by closing the
connection using linger (this will BLOCK the close operation).

Hello,
In the OnDocData of THttpCli descendent, I pause the THTtpCli and
Send(Buffer, Len) to the THttpConnection (this is a proxy server). The
problem is at ConnectionDataAvailable of THttpConnection, I cannot be sure
that all the data is sent or is it complete because sometimes packets are

Re: [twsocket] Need help with HTTP
Hello,
I have debugged the code to this point:
{ 26/11/2003: next 2 lines commented out to allow receiving data outside }
{ of any request (server push) }
{if FState httpWaitingHeader then
Exit; }{ Should never occur ! }
while FReceiveLen 0 do begin
I := Pos(#10, FReceiveBuffer);
if I = 0 then begin
break; // HERE
end;
This occurs when I reuse the same THttpCli connection, first HEAD then GET.
I call InternalClear() and set the state to httpReady in between. I also
check for any disconnection and abort then.
I saw in OnDocData, header being in the Buffer variable. And in this code,
there is no header/just data in FReceiveBuffer. I am puzzled and suffer a
headache. ;0(

Hello,
First of all, I would like to thank Ronny for his kind words on private
email. (He finds my messages helpful! :) ). After a week of bug hunting I
found the problem: I no longer call Abort() if the existing connection's
IP/port is different than target's--I just let the component manage it.
