Hello, I have to consider four scenarios: 1) http://img230.imageshack.us/img230/4172/52435275.jpg 2) http://img2.imageshack.us/img2/6708/42467335.jpg 3) http://img213.imageshack.us/img213/3600/77675899.jpg 4) http://img84.imageshack.us/img84/7221/12837089.jpg Host is connected only to one proxy (I think it does not matter to which one). But proxies servers are connetected to each other. The question is, on which proxy server the website requested will be cached (and why)? Unfortunately I do not have RAM memory enough to install two (or three in some cases) virtual machines with Squid, so I would much appreciate your answers. My answers: 1) when 1&2 doesn't have website requested: - 1 & 2 cached the website 2) when 1&2 doesn't have website requested: - 1 or 2 /it depends where the host is connected/ requests the website and cached it when 1 has the website requested, but host is connected to 2: - 2 requests website from 1, and cached /two servers cached after all/ when 2 has the website requested, but host is connected to 1: - 1 requests website from 2, and cached /two servers cached after all/ 3) when 1&2&3 doesn't have website requested: - the website is cached 3 and 1 or 3 and 2 /it depends where the host is connected/ when only 3 has the website - the website is cached 3 and 1 or 3 and 2 /it is copied from 3/ when 1 or 2 has the website - the website is cached only 1 or only 2 or 1 and 2 or 2 and 1 /it depends where the host is connected/ 4) the same situation as in 2 Please, help Konradoz
