This has come out of bug 38488. (I copied the OS settings from bug 61119). This may end up being the same problem, but I'm splitting that bug up so that we can check. For people who are having problems using the default settings of http/1.1 and with keepalives enabled: a) What version of ms proxy server are you using? b) What version of mozilla are you using? c) What sort of problems are you seeing? If you get an error message, copy and paste that error message _in full_, and mention if you always get it, only sometimes, etc. d) Does your proxy require a username/password login? e) Does mozilla work if you set the http version to 1.0, but leave keep-alives enabled? f) Does mozilla work if you disable keep-alives, but leave the http version set to 1.1? g) Does mozilla work if you disable keep-alives and set the http version to 1.0? h) Does IE5.5 (preferably SP1) work if you enable its option to use HTTP/1.1 to talk to proxy servers? If you have local administrator access on your windows machine (or root on a linux machine), installing ethereal (http://www.ethereal.com/), and doing a packet trace of each of these situations (including the 1.1/with keepalive, and the IESP1 with http/1.1 enabled to proxies) would be really useful. If h) gives the same error as mozilla, then its a proxy server bug. I'm going to try to find an MS proxy server here.
I have no idea what proxy server we're using actually. I'm just assuming it's from MS, because everything else in here is from MS as well. I've tried the pointers given to me by someone in the previous bug, but that doesn't work. It's an authenticating proxy. OK. Here come the answers, point by point. a) don't know (company owned) b) This is build ID 2001080110 c) I'm having trouble reproducing it, so i can't tell right now. It happens, although not as often as a few months ago. It complains about a request not in HTTP-standard or something. I'll come back when i get the error again. d) Yes, it does. e) Yes f,g,h) I'll get back to you on that.
If you were having problems after POSTing forms, then bug 87817 may be your problem.
Sounds interesting. Do you have an URL where i can test this without actually subscribing to anything? ;-)
Got one! This is the error message: ----- 502 Proxy Error The WWW proxy was unable to forward the request to the destination server Your client has attempted to perform a request in a manner not allowed by the HTTP protocol standard. If you are using Microsoft Internet Explorer, make sure the "Use HTTP 1.1 through proxy connections" option is disabled, and click reload to try again. This error may also be caused by using MIE version 4 without Service Pack 2 (or HotFix #2798) installed. ----- I'm going to try (f) now.
OK. Problem confirmed with f. Answer is yes. I already know g. This work without problems. I'm gonna try IE now. (using version 5.5) !!! Stopped sending. I hope this doesn't get posted twice. IE is even worse! It can't even load a single page correctly with this setting on. Half the pictures are missing (userfriendly.org) and it gives the error messages about 25% of the time. (Problems with Bugzilla. If this message appears 3 or more times, you'll know why)
If IE has the same problem, then I'm going to claim that this is a proxy bug. HTTP is designed to be forwards compatible. I don't know exactly what it breaks, because I don't have access to a test server (I'd need to sniff both mozilla<->proxy and proxy<->server). Darin, do we want to do detection based on the via line, or something?
i'm not sure that sniffing proxy servers is the right solution. we probably just want to do something much simpler like expose the "use HTTP/1.0 pref" in the proxy configuration preferences panel with a description of why this may be necessary.
'we probably just want to do something much simpler like expose the "use HTTP/1.0 pref" in the proxy configuration preferences panel with a description of why this may be necessary.' That, and put a note about it in the Release Notes.
I'm going to mark this as QA wanted until we get packettraces. I'll update the relnotes to include msproxy, though. If anyone can point to some docs/an ms kb article/anything, that would help a lot.

FUTURE until we work out what is going on, since this isn't a mozilla bug if ie is affected too.

a) I don't know, it's company owned, I may be able to find out with some diging. b) 0.9.4 (Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.4) Gecko/20010913) 0.0.3 also displayed this problem. 0.9.2 (Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.2) Gecko/20010628) does not have this issue, so it has been my daily browser in the office. c) I receive random proxy errors. When it occurs, the page can be displayed if it is reloaded several time, most of the time that is. This is the error: The WWW proxy was unable to forward the request to the destination server Your client has attempted to perform a request in a manner not allowed by the HTTP protocol standard. If you are using Microsoft Internet Explorer, make sure the "Use HTTP 1.1 through proxy connections" option is disabled, and click reload to try again. This error may also be caused by using MIE version 4 without Service Pack 2 (or HotFix #2798) installed. d) Yes the firewall requires authentication. e) With http to 1.0, with keep-alives enabled, I am receiving the same proxy errors that I was with the default Mozilla setting. It took a restart of the browser to get it working correctly again (keep-alives disabled, and the http version set to 1.1). f) After two days of use, Mozilla is working flawlessly With keep-alives disabled, and the http version set to 1.1. g) Mozilla is also working fine with keep-alives disabled, and the http version set to 1.0. h) IE 5.00.3315.1000 will sometimes throw the same error as above, when "Use HTTP 1.1 through proxy connections" is checked. I may be able to get a packet trace one these situations soon, I just haven't had the time yet.
OK. Given all that we can just mark ms proxy server as broken. A packet trace would still be nice, though, just to confirm. 1.0 probably doesn't work since the cache headers are almost certainly not being removed like junkbuster does Relnote text, under the junkbuster bit: "This problem also affects microsoft proxy servers (bug 94753). In general, if you see pages loading from different servers, first try disabling keep-alives." Marking INVALID.

thelner: what proxy server are you testing? is it MS proxy?
Yes, it is an MS proxy. Unfortunately I don't know the version, patch level, or much else about it. It's company owned, and they aren't giving me much info.
interesting, well if you ever find out please let us know. thanks!
This appears now, that this is most problematic on redirects. There is an article on IE's problem with this here: http://support.microsoft.com/directory/article.asp?ID=KB;EN-US;Q193489 I don't know enough about this, to know if the info in the article is relatable to Mozilla or not, but the symptoms are similar. The following is some of a trace where mozilla would throw the proxy error when it was getting the redirect. I hope it helps. ################################################### #### Mozilla - HTTP 1.1 and Keep Alive enabled #### ################################################### GET http://go.microsoft.com/fwlink/?LinkId=661 HTTP/1.1 Host: go.microsoft.com User-Agent: Mozilla/5.0 (Windows;
