That is, when configuring Squid for transparent caching, why do we need to forward HTTP from Port 80 to Port 3128? What makes it necessary? If we just let Squid to listen on Port 80, what would make the difference. Can anyone help answer this question? Thanks, Shan When you configure Squid to work as a transparent it gets the ability to understand http queries in two different protocols: as an http server and as an http proxy. The client is not aware that the proxy is in the middle of it's connection. So it will speak as if it were talking to an http server in the internet. So, for example, it will try to tcp connect using http protocol to an ip at 8.8.8.8:80 Even if you put squid to listen on port 80 on your gateway, the client is asking to connect to 8.8.8.8:80 in the internet, the connection will be routed there. So, using the extremely powerful linux firewall, you are to redirect that connection to the correct IP:PORT your squid is listening. In a sense you are changing the destination IP of the connection, like a -j DNAT. This is different to the case where the client know of the proxy existence, and does a connection using proxy protocol to the proxy IP:PORT, and no redirection is needed. Regards Sebastian

I can provide more logging info, if needed. Hello Michael, Sometimes is usefull to see how the server puts the http headers to understand why squid doesn't cache certain objects. I usually use wget -S at the squid server $export http_proxy="http://localhost:port"; ; wget -S http://some.site/object Regards Sebastian
Re: [squid-users] Squid 2.7 problem with url
Clue #1: Via: 1.1 cache:31280 (Lusca/LUSCA_FMI) This appears to be Lusca. Not Squid. Lusca is a commercial branch of Squid-2.7. Please contact Xenion for Lusca support. Amos Sorry, downloaded from google code, compiled, and installed, didn't know that it was commercial and/or it was far away from squid. Thanks Sebastian
[squid-users] Squid 2.7 problem with url
Hello Going though squid in transparent mode This url is loaded as text in the browser: http://200.123.152.55/cgi-bin/ft.exe?q=images/edgedesk-logo-big.gif&site=clientes Without squid loads an ugly images, but it loads. I have used wget -S to see server headers, and they both put the content-type. Now I notice that using squid even says Lenght, but connecting to server doesn't. Does anybody have any clue? Thanks in advance, Sebastian Ex: With squid: root@cache:/var/tmp/test# wget -S "http://200.123.152.55/cgi-bin/ft.exe?q=images/edgedesk-logo-big.gif&site=clientes"; --2012-03-09 17:41:13-- http://200.123.152.55/cgi-bin/ft.exe?q=images/edgedesk-logo-big.gif&site=clientes Connecting to 127.0.0.1:31280... connected.
