Duplicate headers received when using temporary bypass

[thanegill]

The response from the server contained duplicate headers. This problem is generally the result of a misconfigured website or proxy. Only the website or proxy administrator can fix this issue. Error code: ERR_RESPONSE_HEADERS_MULTIPLE_LOCATION

Using IP auth with a temporary bypass link. Works in safari on OS X, But nowhere else.

Built with:  '--prefix=/usr' '--sysconfdir=/etc' '--localstatedir=/var' '--mandir=${prefix}/share/man' '--infodir=${prefix}/share/info' '--enable-email=yes' '--with-proxyuser=e2guardian' '--with-proxygroup=e2guardian' '--with-filedescriptors=65536' 'CXXFLAGS=-DFD_SETSIZE=65536'

Please, can you make a try with a browser plug-in like LiveHTTPHeaders (firefox)

[thanegill]

This is my go at LiveHTTPHeaders on chrome: The first is the initial request, and the second the just seems to be blank, meaning no requests.

I don't think that LiveHTTPHeaders was even receiving the headers. These are the response headers that I got out the the wireshark capture (there's an updated version above that includes the response that the initial one didn't have.)

One possibility is that the extra CRLF ("\r\n") after the location header in the 302 redirect is what is causing the problem. In RFC 2616 according to the last paragraph is section 4.1 it's states that HTTP/1.1 clients should not follow any requests that have an extra CRLF.

Can you make a short test with http://numsys.eu/TMP/e2guardian.zip
There is always the extra CRLF ?

[thanegill]

Just tried it. Having the same issues.

[fredbcode]

\r\n ?

Ok I found something, please make a try with http://numsys.eu/TMP/e2guardian.tar.gz

Works with seven - firefox 30 and IE10 -

[thanegill]

Tested and works in Firefox 31.0 for OS X, Safari 8.0 for OS X, Chrome 36 on Windows, IE11 on windows.

Does not work on Chrome for OS X. Might be a bug in Chrome...
