Hi, I could not see any cache_peer entries in your squid.conf. It should be something like this: cache_peer 127.0.0.1 parent 8080 0 no-query originserver name=testsite Also define an acl like this: acl ts dstdomain testiste.zehndercom.org Apply the acl on your host like this: cache_peer_access testsite allow ts With this, if you type the full url :http://testiste.zehndercom.org, it will fetch the page at http://127.0.0.1:8080. However, if you want your users to go to some other path than the document root, such as http://127.0.0.1:8080/path/to/folder/, then use url rewriter to give a response like this: 302:http://testiste.zehndercom.org/path/to/folder For more details look at 2.6 config manual and faq link on redirector both at squid-cache.org cheers!
