Hi Henrik, As you mentioned in your previous email to me (please refer to belowemail), cachemgr works fine if I disable authentication (NTLMauthentication). Below is my authentication acl acl AUTEAM src 172.26.0.0/16acl AuthorisedUsers proxy_auth REQUIREDhttp_access allow AUTEAM AuthorisedUsers Even if I add the below ACL on top of the above three ACL's it isstill not working: acl AUSV 172.26.x.x/255.255.255.255http_access allow Only with the below configuration I am able to logon to cachemgr page(Disable NTLM authentication) acl AUTEAM src 172.26.0.0/16http_access allow AUTEAM Is there a way I can configure squid to allow one IP address172.26.0.1 to access cachemgr page without using NTLM authentication. I just want to access cachemgr page from 172.26.0.1. Thanks. > While trying to retrieve the URL: cache_object://172.26.11.150/> The following error was encountered:> Cache Access Denied.> Sorry, you are not currently allowed to request: cache_object://172.26.11.150/from this cache until youhaveauthenticated yourself.> You need to use Netscape version 2.0 or greater, or Microsoft InternetExplorer 3.0, or an HTTP/1.1 compliant browser for this to work.Please contact the cache administrator if you have difficultiesauthenticating yourself or change your default password. > Looks like your request was denied due to proxy authentication required. > Make sure your cachemgr rules are first, before any other http_access > rules requiring authentication. >> Regards > Henrik
