How can I see what zone or site of origin caspol considers a piece of code to belong to?

I am trying to get used to caspol because the downloaded projects for software books I use invariably won't run because "the project location is not trusted". I understand I need to use caspol to resolve this by creating a membership condition. MSDN caspol documentation recommends not using a URL. How I can't see how I can view the zone or site of origin that caspol considers a piece of code to be associated with. (Yes, I know what site I used, but this has been a consistent issue under x64 Win 7 and I want to know what caspol thinks the ans开发者_运维问答wer is, I certainly don't know what zone the code is in).

As a side note, I am not even sure if I was using the URL what the proper URL would be, is it the location of the solution file, the directory containing the source files, what?
