I think that the official Qt documentation offers a solution for your request [qt-project.org]:

An alternative to setting an application wide proxy is to specify the proxy for individual sockets using QAbstractSocket::setProxy() and QTcpServer::setProxy(). In this way, it is possible to disable the use of a proxy for specific sockets using the following code:

1.  serverSocket->setProxy(QNetworkProxy::NoProxy);

Thanks for your suggestion , but I am not using any QTCPSocket/QAbstractSocket/QTcpServer at all.
I am just using QWebview to load my url. and we can’t call this function(setProxy) on QWebView.

so probably this is not the way to achieve this.
Please share if you have any other thought

Have you seen this thread at stackoverflow [stackoverflow.com]?

It highlights the documentation about QWebPage [qt-project.org] and method setNetworkAccessManager [qt-project.org]:

Note: It is currently not supported to change the network access manager after the QWebPage has used it. The results of doing this are undefined.

The recommended solution at stackoverflow.com [stackoverflow.com] to create QNetworkAccessManager, set up a proxy and then to pass it to the web page seems reasonable.

Thanks a lot leon!!!!!!!!!!!!

You made my life really cool.
I am being able to set the different proxy for different Qwebview inside a single application.
your solution simply rockzz!!!!!!!!

You are welcome :) I am glad that the issue was solved but please note that I got the idea from a thread at stackoverflow.com [stackoverflow.com].
