Hi, can we get the attachment you are talking about?
Which version of QtWebkit, on which device, with which version of Qt ? What kind of test application? What kind of access point we are talking about? Is it behind firewall? etc..

XMLHttpRequest works, a lot of problems reported relate to wrong security settings. So to reproduce this issue we need more information.

Qtwebkit version: qtwebkit 2.1.1 week 09

On device, keep the single access point(GPRS or WiFi)

test html page has been attached already

It is already a P1-blocker.
If you need it immediately, you should find someone who can look at the bug.

[Johannes Oikarinen]

The root cause of this issue is found in QtNetwork QNetworkReplyImpPrivate class. The class doesn't maintain correct state for synchronous requests; synchronous requests are set to finished already at the beginning of the request. Wrong state blocks the QNetworkReply from emitting finished signal when the request actually completes. Since no signal is emitted an eventloop in ResourceHandle::loadResourceSynchronously hangs at Webkit’s side.

Webkit might need to have an additional check to see if the QNetworkReply contains any unread data before closing it. This is needed since a response can be received from a remote host before Webkit connects handlers for the QNetworkReply. QNetworkReplyHandler::finish could be suitable place to implement this.

The sample html provided here shows the XML 101 Error across all browsers. (Chrome, Safari, Firefox and QtTestBrowser).

Tried the original test (part of widget) in the Qt-5061. Unable to reproduce on QtTestBrowser (based on Qt 4.7)
