a whitelist for outgoing syn port 80, 443 traffic for hosting

[Ken A]

Hello,

Is anyone aware of a whitelist of hostnames of port 80,443 OUTGOING 
traffic that should be considered 'normal' in a hosting environment?
ie: SYN traffic to ups.com, authorize.net, technorati, for ecommerce, 
blogging, etc..

Categorizing traffic as good/bad is useful in this day of many php 
remote file include bugs.

Thanks,

Ken A.
