Ok, after banging my head for another day, I still can't figure out if I am doing anything wrong. I realized that I am using Qt 4.5.2 so it could very well be a bug.

In Qt 4.5.3 change log I see this

QNetworkAccessManager
* [256240] Proper handling of HTTP redirect in AlwaysCache mode.
* [257662] Fix timing issues that could trigger double sending of an
HTTP request.

Please suggest if these bugs were related to QHttp too ? Should I use QNetworkAccessManager instead with the latest version 4.5.3 ?

they were not.

Should I use QNetworkAccessManager instead with the latest version 4.5.3 ?

yes QHttp is deprecated with the soon to be released Qt 4.6.

For QHttp too I did receive 200 OK response..but the file was not uploaded. What is it that curl is doing different so that the file gets uploaded ?

[ct]

The only difference I see is Expect: , could it be this ?
