QTcpSocket proxy authentication problem

[arbi]

yes i tried that class also . but i couldnt get it work. Maybe i am using that wrong.

When using QTcpSocket i connect to the proxy server.

s.connectToHost("yy.yy.yy.yy",8080);// yy.yy.yy.yy:8080 is the proxy address

s.connectToHost("yy.yy.yy.yy",8080);// yy.yy.yy.yy:8080 is the proxy address

To copy to clipboard, switch view to plain text mode 

and send server the message below;

POST http://xx.xx.xx.xx/ HTTP/1.1
User-Agent: TSS Client
Host: xx.xx.xx.xx
Proxy-Connection: Keep-Alive
Content-Length: 61
Content-Type: application/timestamp-query
Identity: 304d0201010410a6ee0e6ddf04fd7e0f36a41708071a850202 07d004105f0ffc985e9c03361f5e11d8bf674e10042007320d c4190c712f1dfb94ced2e983a886674d2a9600ca3fec5e5c56 31e9d73c

how can i do the same with QNetworkAccessManager?
I read the doc about QNetworkAccessManager;
I set the proxy of manager with setProxy() and tried post(...) method with several combinations , connected all of the signals it emits to slots. but couldnt see anything coming from the server.

can you explain how can i use QNetworkAccessManager to make the above request.?
How should i init QNetworkRequest object when posting? should i post to my destination(xx.xx.xx.xx)
or the proxy server(yy.yy.yy.yy).

a piece of code ?

thanks.

Generally speaking you have to query your destination directly, and set the proxy ip/user/pass in QNetworkProxy .

But..I usually work with QNetworkAccessManager behind a ISA proxy when I'm testing my app at work, and I can't connect to the proxy server directly because...my ISA server uses NTLM v2 hashes and Qt don't support them.
At least until version 4.5 (from QAuthenticator documentation):

QAuthenticator supports the following authentication methods:

Basic
NTLM version 1
Digest-MD5
Note that, in particular, NTLM version 2 is not supported.

To my surprise version 4.5.2 misses this notice, but you can read from google cache: http://209.85.129.132/search?q=cache...&ct=clnk&gl=it

It doesn't seem that nokia improved qauthenticator (at least there's nothing about it in 4.5.1 and 4.5.2 changelog), and anyway it it still not working for me.

There IS a solution indeed, at least for your development machine: use CNTLM on your computer, and point your qt app to the following proxy "localhost:3128" (that is default cntlm port).
Obviously you need to configure and run CNTLM before

Hope this helps
