Custom URL Category setup

[tahscolony]

Probably a simple answer to this question. If a site, say Google.com has both http and https, is there anything special I need to do to allow both sites?  Is all I need for this is  google.com and .google.com?   Or do I need a regex of http?://.*google\.com instead for https?

Is the Regex only needed when you have child domains such as apps.google.com, and maps.google.com, or something like http?://.*fanniemay\.com?

Trying to replace an old outdated proxy with Ironport and transferring the whitelist is giving me a headache. It has URL's that have *domain.com:443, domain.com:443*,  *domain.com, and domain.com*, but none that would transfer to Ironport without modifying them.

Just trying to determine when and where I need a regex instead of just the plain .domain.com

google.com and .google.com will work for http and https

.google.com will work for any sub-domain in google such as apps.google.com since '.' in front will work as a wild card.

in newer version the regular expressions may not begin or end with '.*' and cannot end with '\'

So if I want to match anything google. What is the difference between google.com by itself or .google.com by itself. Shouldn't either one match www.google.com? Or mail.google.com
