Adapting “hosts” file block lists to Privoxy's way of blocking…

[Faxopita]

In order to differentiate a top or second-level domain from the rest of the address, I've made the script to rely on the most common generic extensions. It's a personal choice and found it fair enough for me. However, someone could use instead the provided in-archive SLD.txt file—which currently contains 7313 domain extensions—and make the script rely on it.

Script portion dealing with domain extensions:

Code:

\(\.[a-z0-9]\{2\}\(\.[a-z0-9]\{2,3\}\)\?\|\.[a-z0-9]\{3\}\(\.[a-z0-9]\{2\}\)\?\|\.[a-z0-9\-]\{4,\}\|\(\.xn--[^\.]\+\)\{2\}\)$

Sources of domain extensions:

• http://www.domaininformation.de/tld_list.html
• https://github.com/gavingmiller/second-level-domains
• https://www.iana.org/domains/root/db
• https://data.iana.org/TLD/tlds-alpha-by-domain.txt
• http://www.newtldlist.com/
  

The most exhaustive one though seems to be: https://publicsuffix.org/list/public_suffix_list.dat

File SLD.txt is based upon this latter list.
