But this happens on Windows XP and Vista, and Windows 9x is no longer
supported, right? FYI: I'm not even on windows, but I do use a spoofed
HTTP UA.
Important new features, like an improved phishing detector for both mail
and the browser now simply fail because of this bug.
Also, the JS component observes "http-on-modify-request" and QI's into
nsIRequest.name because nsIHttpChannel.referrer can be blocked or null,
but look at that comment in the IDL; "Often this is the URI of the
request." so how else do I get to the URI from nsIHttpChannel?
Next problem: How do I get to either the document, docShell, window or
tab which initiated this request/channel?
There should only be one component changing the HTTP requests, that I
read in the IDL, so how do I filter stuff out? For example, we use
something like:
if (/^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/.test(currentHost)) {
but isn't there anything else that A) works faster and B) is ipv6
compatible that I can call from some interface?
Thank you for your help,
