Hi all!
I've configured my proxies correctly, and now they work as expected.
* Requests to fast sites get forwarded to ProxyA, which uses FastInet
* Other requests gets handled directly by ProxyB and ProxyC, which uses
SlowInet
There's a problem, however, that recently cropped up.
I've added ".google.com" and "mail.yahoo.com" as a fast sites.
Accesses to Google and Yahoo Mail (mail.yahoo.com) gets accelerated, as
expected.
However, when trying to access the Google cache, apparently the URL uses
an IP address instead of a domain name, e.g. "72.14.192.66"
Same situation happened when accessing an attachment in Yahoo Mail, it
uses an IP address instead of domain name, e.g. "206.190.39.216"
I keep getting errors:
===== Error message snip =====
The following error was encountered:
* * Unable to forward this request at this time. *
This request could not be forwarded to the origin server or to any
parent caches. The most likely cause for this error is that:
* The cache administrator does not allow this cache to make direct
connections to origin servers, and
* All configured parent caches are currently unreachable.
===== Error message snip =====
I think ProxyB and ProxyC somehow performed a reverse DNS, and forwards
the IP-address-based requests to ProxyA, while ProxyA only allows
explicit URLs in its miss_access directive.
I've tried editing the ProxyA's squid.conf like follows:
#snippet of ProxyA squid.conf
acl fastsites dstdomain .yahoo.com
acl fastsites dstdomain .yimg.com
acl fastsites dstdomain .yahooapis.com
acl fastsites dstdomain .google.com
acl fastsites dstdomain .gmail.com
acl fastsites dstdomain 206.190.39.216
#
acl fastsites_ip dst 72.14.192.0/18
acl fastsites_ip dst 206.190.39.216
#
miss_access allow fastsites
miss_access allow fastsites_ip
miss_access deny siblings
But to no avail.
Any suggestions?
Does adding the IP-text "206.190.39.216" to the dstdomain ACL work?
Squid should try an exact text match before doing rDNS.
Otherwise you may be stuck with an url_regex pattern for those.
