Hello,
we use squid3.0 stable4 on SLES10.
It was compiled with followed parameters:
./configure --prefix=/usr/local/squid3 --enable-icap-client

--enable-err-languages="Russian-1251 Russian-koi8-r"
--enable-linux-netfilter --disable-ident-lookups
--with-default-user=drweb
When we try to view URL http://wiki.mozilla-russia.org through the
proxy, we receive error message.
We enter squid in debug mode and receive followed messages:

As you can see squid put IP: aaa.bbb.ccc.ddd (a squid ip address)
to the dynamic link instead of real domain name of the site
(wiki.mozilla-russia.org)
We don't understand why?
Please, help us to solve this problem.
Best Regards,
Alex
Not squids fault. The "Server: nginx/0.6.29" is sending a 302 out
with bad information.
What happening there is:
-> First request has domain + URI.
<- Squid contacts 195.18.35.94 for data
-> 195.18.35.94 (nginx/0.6.29) redirects: 302
http://aaa.bbb.ccc.ddd...
-> Second request has aaa.bbb.ccc.ddd + new URI
<- Squid contacts aaa.bbb.ccc.ddd for data
-> failure.
If the server 195.18.35.94 is yours it needs its redirector fixed.
Amos
Hello, Amos.
Thank you for your answer.
The server 195.18.35.94 is not ours. It is
http://wiki.mozilla-russia.org.
We think that the problem in http://wiki.mozilla-russia.org, but we
are not sure.
I allready understood that 195.18.35.94 redirect the request.
I don't understand why.
In direct request (without squid (aaa.bbb.ccc.ddd)) the server
195.18.35.94 (http://wiki.mozilla-russia.org) redirect request to
itself:
http://wiki.mozilla-russia.org/index.php/ru/%D0%91%D0%B0%D0%B7%D0%B0%20%D0%B7%D0%BD%D0%B0%D0%BD%D0%B8%D0%B9%20%D0%BF%D1%80%D0%BE%D0%B5%D0%BA%D1%82%D0%B0%20Mozilla%20%D0%A0%D0%BE%D1%81%D1%81%D0%B8%D1%8F
When we use squid it redirect to squid ip:
http://aaa.bbb.ccc.ddd/index.php/ru/%D0%91%D0%B0%D0%B7%D0%B0%20%D0%B7%D0%BD%D0%B0%D0%BD%D0%B8%D0%B9%20%D0%BF%D1%80%D0%BE%D0%B5%D0%BA%D1%82%D0%B0%20Mozilla%20%D0%A0%D0%BE%D1%81%D1%81%D0%B8%D1%8F
Of couse, the URL http://aaa.bbb.ccc.ddd/index.php/ru/...... is not
exist.
Alex.
I managed to replicate the behaviour without using squid at all.
The ngix server appear to be dying whenever it receives
X-Forwarded-For: header.
You can temporarily plug this break with:
acl brokenXFF dstdomain .mozilla-russia.org
request_header_access X-Forwarded-For deny brokenXFF
Amos
Thank you for your answer, Amos.
After adding the acl you've wrote all works fine.
