# Rule file for the plugin urlfilter-fast

# Used to filter a large number of domain and host-specific regular
# expressions

#
# `Domain` rules are applied to all hosts and subdomains of a domain, e.g.
#
#   Domain example.org
#     DenyPath (?i)%7c                # matches against just the path part of URL
#     DenyPathQuery ^/resource\?x=1   # matches against path + query
#
#
# To match against a single hostname:
#
#   Host www.example.com
#     DenyPath (?i)%7c
#
#
# Global rules are defined using the domain name `.`:
#
#   Domain .
#     (/[^/]+)/[^/]+\1/[^/]+\1/
#     # skips URLs with slash-delimited segment that repeats 3+ times, to break loops
#
#
# Comments start with the `#` character and reach until the end of the line.
