Because the web page is coded to require and redirect to HTTPS, I can not terminate at Squid without the development team recoding the page. That will be done at some point but I would like to test it first with allowing SSL to the back end server. I see from the FAQ page that I have these options:
1. The browser opens an SSL connection directly to the origin server. I do not want this as I want to use the cache for images. 2. The browser tunnels the request through Squid with the CONNECT request method. Will caching work with this? How is this setup?

Squid needs to be configured with the ssl option. For a simple test you can type: openssl req -new -x509 -nodes -keyout squid_key.pem -out squid_cert.pem to generate a self signed cert. Do this in your squid's etc directory and then something like: https_port 443 vhost cert=/path_to_squid/squid/etc/squid_cert.pem key=/path_to_squid/squid/etc/squid_key.pem vhost We decided not to put SSL on the actual webserver. Traffic between our site and the end user is encrypted via the SSL so we saw no need to put an extra burden on the webserver too. The above is on squid-3, btw.

What cert would I use for the SSL form Squid to the web server? The same cert? How would this be setup? I can't find any documentation about how to setup most of the SSL (HTTPS) configuration. I do have The Definitive Guide, but only a small section about SSL (HTTPS) on page 304. -----Original Message----- From: Henrik Nordstrom [mailto:[EMAIL PROTECTED] Sent: Thursday, August 19, 2004 6:12 PM To: Brad Taylor Cc: [EMAIL PROTECTED] Subject: Re: [squid-users] SSL and Reverse Proxy On Thu, 19 Aug 2004, Brad Taylor wrote: > I'm trying to setup Squid as a reverse proxy with SSL.

To proxy the SSL needs to be terminated. What you can do if you do not want to terminate the SSL and have it running all the way back to the web server to tunnel the SSL using a simple TCP plug or NAT/Port-forwarded. > Can I have the cert on both the Squid and IIS web server but when I hit > the Squid box with https://IP_address_of_squid I get sent to > https://IP_address_of_IIS_web_server therefore it is not getting > anything from cache. This is possible with Squid-3 (or Squid-2.5 with SSL update and a bit of tinkering). But please note that in such configuration the SSL is terminated at the proxy and then a new SSL is opened between the proxy and the web server. In most configurations this second SSL is not really needed but you have the choice. Squid-2.5 (without SSL update) can only terminate SSL connections, acting as an SSL server. It can not initiate SSL connections. Regards Henrik
