Hello all, I have configured squid-2.6STABLE1 as transparent proxy in my linux machine. It is working without any error. But i am getting a warning mesage in my cache.log saying it has detected a Forwarding loop. My relevant squid.conf is as follows: http_port 8888 transparent cache_peer 172.16.1.49 parent 8888 0 no-query http_access allow all Do we need cache_peer option to setup for transparent proxy. When i use the cache_peer option iam getting the following entries in my cache.log ----------------------------------------------------------------------------------------------- 2006/07/12 11:24:53| WARNING: Forwarding loop detected for: Client: 172.16.1.49 http_port: 172.16.1.49:8888 GET http://www.jboss.com/modules/bb/templates/subSilver/images/lang_english/icon_www.gif HTTP/1.0 User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Opera 7.50 [en] Host: www.jboss.com Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1 Accept-Language: en Accept-Charset: windows-1252, utf-8, utf-16, iso-8859-1;q=0.6, *;q=0.1 Accept-Encoding: deflate, gzip, x-gzip, identity, *;q=0 Referer: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3957225 If-Modified-Since: Mon, 10 Jul 2006 05:04:16 GMT Cookie: JSESSIONID=460C69EB4C78A020532BEEAC379C8519 Cookie2: $Version=1 Via: 1.1 vimailfilter:8888 (squid/2.6.STABLE1) X-Forwarded-For: 172.16.1.40 Cache-Control: max-age=259200 Proxy-Connection: keep-alive ------------------------------------------------------------------------------------- If i comment the cache_peer option iam getting the following error message in my browser. ------------------------------------------------------------------------------------- ERROR The requested URL could not be retrieved While trying to retrieve the URL: http://www.google.co.in/ The following error was encountered: * Unable to forward this request at this time.
