[squid-users] Squid and HTTP/1.1 303 See other

Hello everybody,

simplistic description of my problem : squid seems confused when
receiving a HTTP/1.1 303 error code.

Here is the full description : i've got a http client (157.99.64.54)
accessing a toshiba printer web interface (france.hopital.pasteur.fr /
157.99.176.25).

When my client (firefox) connect to france.hopital.pasteur.fr WITHOUT
using squid, everything is fine There is a
redirection after the HTTP/1.1 303 to 157.99.176.25:8080 (see
firefox-direct.pcap). I can see it in my adress bar and i access to the
web interface.

When my client connect to france.hopital.pasteur.fr THROUGH squid, i've
got this error :

"Invalid Response error was encountered while trying to process the request:

    GET / HTTP/1.1
    Host: france.hopital.pasteur.fr
    User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.15)
Gecko/20101028 Iceweasel/3.5.15 (like Firefox/3.5.15)
    Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
    Accept-Language: en-us,en;q=0.5
    Accept-Encoding: gzip,deflate
    Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
    Keep-Alive: 300
    Proxy-Connection: keep-alive
"

The corresponding pcap file is firefox-squid.pcap. I've got a HTTP/1.0
502 Bad Gateway. The corresponding pcap file on the squid side is
squid-toshiba.pcap. I can see the HTTP/1.1 303, but nothing else.

If i use http://157.99.176.25 it does not work either, but if i specify
the port (http://157.99.176.25:8080) i've got no problem.

Chrome/Chromium seems to encounter the same problem. I try to connect to
http://france.hopital.pasteur.fr WITHOUT squid, i've got the same
behaviour (and similar pcap file) : i receive HTTP/1.1 303 and nothing
else append.

The pcap files:

http://dl.pasteur.fr/fop/AjvBeYu8/firefox-direct.pcap
http://dl.pasteur.fr/fop/XwBDAABP/firefox-squid.pcap
http://dl.pasteur.fr/fop/jhQdWnsD/squid-toshiba.pcap

Any hints is welcome :)

Regards,

Jean-Baptiste
