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.
