A step by step testcase to be called on a SSL-webserver through a HTTP proxy(non localhost)

Subject:
The following steps demonstrate a bug in WebKit when using XMLHttp-POST to a HTTPS-Site via HTTP-Proxy.

Speculation:
Subsequent XMLHttp-POST does not check for a valid Proxyconnection (and reestablish if needed) when sending the Request.

affected Browsers:
Bug occurs on Safari/MacOS and Konqueror/Linux.

not affected Browsers:
Safari/Windows, IE+Firefox+Chrome/Windows/MacOS/Linux

Prerequisites:
    OS non-windows
    Browser using WebKit
    Browser needs to use an HTTP-Proxy for HTTPS-Requests
    Webserver needs to be SSL-enabled (resource needs to be HTTPS-accessible)
    Any HTTP-Proxy (tested with Squid, CCProxy, Paros)
    Proxy needs to be installed on a different machine (localhost proxy does not trigger the bug)
    Request has to be XMLHttp-POST

Steps to reproduce:
    Open this file xmlhttml.html from your webserver in your browser
    Step 1 GET main site
    Step 2 GET subpage from main site
    Step 3 POST to subpage produces No Error
    Step 4 just wait about 3-10 seconds (Proxy connection will close)
    Step 5 POST to same subpage produces Error (proxy connection is not checked/reestablished)

See fully functional demo code attached, also contains instruction how to setup a testing environment (2 machines required)
