RE: [squid-users] RE: Odd requests coming in via Squid servers

Thanks for the reply.

I checked and c.corp.globalenglish.com is not referenced anywhere on our
site, but it is sometimes used by our caching services (Digital Island and
Akamai) to get files from us so that may not be related to the problem.

The URLs were definitely never used on our site. The number is an embedded
version number that always goes up when the file is changed. Some of the
files were ones that have never changed since we put this versioning system
in place. If the files were ever referenced on the site in that way the
problem would be more widespread. The only requests for these files are
coming in via Squid servers.

Thanks,
-Brian

There is nothing known in Squid to cause symptoms like this.

The c.corp.globalenglish.com domain seems to be intentional by your web
site design as this is a DNS registered alias for corp.globalenglish.com.

Regarding the other issue with a number beeing off.. are you sure this is
not a case of references to old versions of the object? There is some
situations where a hierarchy of Squid servers where the clocks are not
running correctly can cause older content than intended to be given to the
clients..

Henrik
