block duplicate URL – possible ?

(if i missed this, my apology, but i didn’t see it in the plugin so i’m posting here)

i’d like to check for duplicate URLs too (if enabled)

this would include subdirectories and subdomains, for example, all the following would be duplicates:

http://www.mydomain.com
mydomain.com
subdomain.mydomain.com
http://www.mydomain.com
https://subdomain.mydomain.com
http://www.mydomain.com/subdir1

the regex would look for “somedomain.com” or whatever legitimate extension like .org or .net or whatever

BUT, the following would NOT be duplicates:

mydomain.com
mydomain.net
mydomain.org

you get the idea

many thanks

happy new year 🙂
