           Summary: Add support to disable "Accept-Encoding:" HTTP header
                    on soup ResourceRequest
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: andrunko at gmail.com


If ResourceRequest::setAcceptEncoding(false) is called we make sure the "Accept-Encoding:" header is not added to the soup message, as this could lead to issues where for example the server sends compressed data and the Content-Length (ResourceResponse::expectedContentLength()) is the size of the compressed data, but the data received in ResourceHandle::didReceiveData() is uncompressed (done by SoupContentDecoder), so the data received has a different size from what is actually reported.

This is especially needed by the webkit gstreamer source element which needs to rely on the correct data size to download streams.

The default value of ResourceRequest::acceptEncoding() is true to keep backwards compatibility.

Patch to follow.
