Hi Rick,

Thanks for your reply, comments below.

OK, I initially thought that it may work purely on the fact that intel.com
is listed so everything under that
domain will be accessible including program.intel.com, which just so happens
to be in the list also.

>As you correctly stated, the entry <intel.com> in a whitelist gives access
to
><every.sub.domain.intel.com/and/every/url>.

whitelist.

That makes sense, and I assumed that was the case, I just wanted some
confirmation from the list.

All it means is that I will have to do some further refinements to my
whitelist removing all subdomains and just listing the top level domain (ie
intel.com) or go through and explicitly list all the subdomains of a site
(www.intel.com, developer.intel.com, program.intel.com etc..)

Thanks for your feedback
