When I am trying to accesses a web page thry browser on the same machine where squid is running, error being logged in access.log is TIMEOUT_FIRST_UP_PARENT. User are being authenticated successfully thru ncsa_auth. Few minuted browser trie to get the web page (with status messaage trying to get the web page) and finally says access is denied by proxy. My setup is like this My head office already has a squid proxy (HEADPROXY=10.10.10.1). Local office has another proxy server (netscape proxy server OLDPROXY=20.20.20.1) running on Windows NT.
