Summary showModalDialog doesn't load page when accessed via Microsoft ISA Proxy Server

1. Verify your browser is configured to access the internet via a Microsoft ISA Proxy Server (if you aren't going through a proxy server - the bug doesn't repro) 2. Navigate to a page that calls showModalDialog (see https://bugs.webkit.org/attachment.cgi?id=20143) 3. On test page, click the "Browser Picker" button 4. On Safari for Windows, the dialog window will appear, but not load page content. Notes: Does not appear to repro on Safari 3.1.2 for Mac OS X Leopard (10.5.4)

I'm pretty sure this is a Safari/CFNetwork bug and not a WebKit bug, so we'll probably want to close this as INVALID. Since this database is only for WebKit bugs. It's surprising, if true, that the same URL will load properly if it's not showModalDialog. So there's a chance this could be a WebKit issue.

Does the proxy use authentication?
