Something similar seems to happen when the proxy blocks ssl.google-analytics.com, so this might not be related to the 302 status at all.
Is Bug 544979 related here?
It looks like so.
IE8 work fine: open page with no delay Proxy redirect all blocked sites/pages to file clear.gif on local server "firewall", with http:// all works fine
What happens if you redirect to a https page ? There are security restrictions for https proxy redirects that could cause this. Blocking the page can block the rendering based on the script, that's normal.
If i redirect to a https page happens infinite waiting for data. Then proxy server restarted=connection close, FF request other files and display page.
Can you post a HTTP log for this problem - https://developer.mozilla.org/en/HTTP_Logging ? I'm seeing similar symptoms with squid replaced by a small snippet of python code, but would like to confirm it's the same issue. (And trying to install and configure squid is not really something most people would want to do just to troubleshoot an edge case problem.)
Proxy redirects are disabled with bug 479880 but allowed again for http status codes with bug 491818 (if i read that right). What happens if you redirect to a document with the right mime-type for a script ?
Log sended to you by email. I can give access to my proxy, or config files to squid and nginx
From comparing HTTP logs, I think this testcase is close enough to the problem Ivan is seeing. To reproduce, run TinyHTTPProxy.py, set proxy in Firefox settings to 0.0.0.0:8000 for all protocols, then open this page via file:///
My and Ivan's logs.
The relevant part of the log in my testcase shows how Necko ends up calling nsScriptLoader::OnStreamComplete without aContext, which causes it to assert and drop the script load request, which I think should lead to the symptoms (script stuck in the loading state forever). -1340452864[d553d0]: nsHttpTransaction::HandleContentStart [this=1db25fe0] -1340452864[d553d0]: http response [ -1340452864[d553d0]: HTTP/1.0 302 Moved Temporarily ... -1340452864[d553d0]: SSL proxy CONNECT failed! -1340452864[d553d0]: nsHttpTransaction::HandleContent [this=1db25fe0 count=0 read=0 mContentRead=0 mContentLength=0] -1340452864[d553d0]: nsHttpConnection::CloseTransaction[this=db8fd0 trans=1db25fe0 reason=80470002] -1340452864[d553d0]: nsHttpTransaction::Close [this=1db25fe0 reason=0] ... -1607481568[d0a9b0]: sending status notification [this=1db25970 status=804b000a progress=0/0] -1607481568[d0a9b0]: nsHttpChannel::OnStartRequest [this=1db25970 request=1e353480 status=0] -1607481568[d0a9b0]: nsHttpChannel::ProcessResponse [this=1db25970 httpStatus=302] -1607481568[d0a9b0]: Cancelling failed SSL proxy connection [this=1db25970 httpStatus=302] -1607481568[d0a9b0]: nsHttpChannel::Cancel [this=1db25970 status=804b000d] -1607481568[d0a9b0]: nsHttpConnectionMgr::CancelTransaction [trans=1db25fe0 reason=804b000d] -1607481568[d0a9b0]: STS dispatch [dd0900] -1340452864[d553d0]: ...returned after 303213 milliseconds -1340452864[d553d0]: nsHttpConnectionMgr::OnMsgCancelTransaction [trans=1db25fe0] -1340452864[d553d0]: nsHttpTransaction::Close [this=1db25fe0 reason=804b000d] -1340452864[d553d0]: already closed ... -1607481568[d0a9b0]: nsHttpChannel::OnStopRequest [this=1db25970 request=1e353480 status=804b000d] -1607481568[d0a9b0]: nsHttpTransaction::DeleteSelfOnConsumerThread [this=1db25fe0] -1607481568[d0a9b0]: Destroying nsHttpTransaction @1db25fe0 -1607481568[d0a9b0]: nsHttpChannel::FinalizeCacheEntry [this=1db25970] -1607481568[d0a9b0]: calling OnStopRequest -1607481568[d0a9b0]: ###!!!

I think Necko is supposed to pass the correct context to nsScriptLoader. What I don't know is where the fix should be - should the stream loader have its OnStartRequest called by that point, or should it just pass the context from the channel (I haven't figured out why it's even stored yet). Biesi?

I have no idea how to write tests for this.. But I can certainly confirm using steps from comment 12. Looks like a regression from bug 491818.

I assume we need this on all the branches too, right?

Comment on attachment 441528 [details] [diff] [review] Fix D'oh! Yup, totally my code and my fault. Thanks to all for tracking it down. And yes, this should be applied to all branches.
Summary: HTTP CONNECT does not propertly handle 302 error → HTTP CONNECT does not properly handle 302 error
Drivers, this seems to be a regression from bug 491818, which in turn was a regression from bug 479880, which was an sg:high bug. It's a one line fix.
(In reply to comment #16) > I have no idea how to write tests for this.. I guess httpd.js should be augmented to allow CONNECT requests.

Thank you, bz! (See bug 492459) My problem is fixed (so VERIFIED as far as I'm concerned).
I have the impression that this bug is not completely fixed. For example if I block etracker.com by my proxy (privoxy 3.0.16) , I cannot any longer access www.kreditkarte.at. Firefox will wait forever for code.etracker.com I am using Firefox 3.5.2 on Windows XP and Firefox 3.6.6 on Windows Vista.
Well, 3.5.2 would certainly not have this fix (and is at least 9 security updates out of date). 3.5.11 should. For some reason the 1.9.2 repo is not showing the push from comment 25 at all. But in any case, I _think_ it would have landed best-case in 22.214.171.124....
Looks like this actually landed on the 1.9.2 branch as http://hg.mozilla.org/releases/mozilla-1.9.2/rev/ba8960ab9acd I still suspect that it'll be in 126.96.36.199, but I'm totally lost in our branch stuff now.
Tested also on 3.5.10. Also here https://www.kreditkarte.at cannot be accessed if etracker.com blocked via privoxy.
> Tested also on 3.5.10. _Please_ read comment 29. The fix is in 3.5.11. It's NOT in any earlier versions. What made you think it was?
Is firefox 3.6.6 supposed to have this fix? It doesn't seem to.
Think I know why my proxy returns 405 errors rather than 302 errors.
> Is firefox 3.6.6 supposed to have this fix? Michael, please read the bug. I answered that question once already...
Boris, when did you answer that? I can't find any comment regarding 3.6.6.
bz refers to comments 29 & 30. 188.8.131.52 is a Gecko version corresponding to Firefox 3.6.7. You can get a build for testing from http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/3.6.7-candidates/build2/
Thanks, Nickolay. Just a note: Normal users don't know the version numbers of the engine and which engine version is in which browser version. So they are only interested in the browser version.
Heiko, my apologies. I was sure the 3.6/1.9.2 discussion included the Firefox version numbers, not just the Gecko ones... looks like I was wrong.

Boris, do you mind if I go ahead and check this in for you on 1.9.0 when I'm doing all the patches for which I requested approval?
Fine by me.
