Hello list, I've been experiencing a perplexing problem. Squid 3.1.12 often times out when trying to access certain sites, most notably MSDN. But it's still very fast when accessing other non-problematic sites. For instance, trying to access the following URL *always* result in timeout: http://msdn.microsoft.com/en-us/library/aa302323.aspx Trying to get the above URL using wget: No problem. I've even opened up the http_access and miss_access: http_access allow manager localhost http_access deny manager #http_access deny !Safe_ports #http_access deny CONNECT !SSL_ports #http_access allow localnet http_access allow localhost http_access allow pans_indonet http_access deny all miss_access allow pans_indonet miss_access deny all ... where pans_indonet is the acl containing the whole network of my company. Any pointers as to what I should check next? Rgds,
msdn.microsoft.com DNS response to AAAA lookup is a successful CNAME, but with no IP addresses to connect to.
The behaviour you describe can appear if you have turned dns_v4_fallback OFF. Which disables A lookup (IPv4 connectivity) if there is any kind of successful AAAA, even a useless empty one like MSDN produces.
Also, "miss_access deny ..." prevents Squid fetching new content from the Internet. It's unclear why you would want to have miss_access in the config at all.
