Custom URL Category Configuration Verification.

[Gareth.Doyle]

Is anyone able to confirm this for me by chance? I'm trying to do some testing, but being able to find independent confirmation would be a nice comfort to me.

In a Custom URL category list, is an entry like:

abc.com/

equivalent to:

abc.com/*

?

Thanks!

Thanks!

Yes. "abc.com/" will match "abc.com/index" and "abc.com/example/index". But it does not match "example.abc.com/index", so if you are trying to include/exclude all of abc.com, you need "abc.com/" and "*.abc.com/" entries.

Thanks, Adrian. We have some cluttered (and extensive) URL categories because of a multitude of instances of abc.com/ and abc.com/* being in the lists for some reason. Likely just lack of proper knowledge on someone's part.

Thanks.

Yeah, I recently did the same, have 20+ custom categories with hundreds of entries in many of them added by different people over the years. Consolidated them down and added proper terminating slashes, haven't seen any issues yet (knock on wood).

Can anyone explain what *.abc.com/* will match? For instance would it match example.abc.com/word/text ?

Gary, They are equivalent. You do not need the trailing asterisk. 
You want the trailing slash to prevent matching abc.com.malware.lol/got-you-now
The KB should be fairly clear and fill in any gaps once you know this.
