+
+Filters URLs based on a file of regular expressions using host/domains
+matching first. The default policy is to accept a URL if no matches
+are found.
+
+Rule Format:
+
+```
+Host www.example.org
+ DenyPath /path/to/be/excluded
+ DenyPath /some/other/path/excluded
+
+# Deny everything from *.example.com and example.com
+Domain example.com
+ DenyPath .*
+
+Domain example.org
+ DenyPathQuery /resource/.*?action=exclude
+```
+
+`Host` rules are evaluated before `Domain` rules. For `Host` rules the
+entire host name of a URL must match while the domain names in
+`Domain` rules are considered as matches if the domain is a suffix of
+the host name (consisting of complete host name parts). Shorter
+domain suffixes are checked first, a single dot "`.`" as "domain name"
+can be used to specify global rules applied to every URL.
+
+E.g., for "www.example.com" the rules given above are looked up in the
+following order:
+
+1. check "www.example.com" whether host-based rules exist and whether one of
them matches
+1. check "www.example.com" for domain-based rules
+1. check "example.com" for domain-based rules
+1. check "com" for domain-based rules
+1. check for global rules (domain name is ".")
+
+The first matching rule will reject the URL and no further rules are
+checked. If no rule matches the URL is accepted. URLs without a host
+name (e.g., <code>file:/path/file.txt</code> are checked for global
+rules only. URLs which fail to be parsed as
+[java.net.URL](https://docs.oracle.com/javase/8/docs/api/java/net/URL.html)
+are always rejected.
+
+For rules either the URL path (`DenyPath`) or path and query
+(`DenyPathQuery`) are checked whether the given [Java Regular
+expression](https://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html)
+is found (see
+[Matcher.find()](https://docs.oracle.com/javase/8/docs/api/java/util/regex/Matcher.html#find--))
+in the URL path (and query).
+
+Rules are applied in the order of their definition. For better
+performance, regular expressions which are simpler/faster or match
+more URLs should be defined earlier.
+
+Comments in the rule file start with the `#` character and reach until
+the end of the line.
+
+The rules file is defined via the property `urlfilter.fast.file`,
+the default name is `fast-urlfilter.txt`.

+/**
+ * Filters URLs based on a file of regular expressions using host/domains
+ * matching first. The default policy is to accept a URL if no matches are
+ * found.
+ *
+ * Rule Format:
+ *
+ * <pre>
+ * Host www.example.org
+ * DenyPath /path/to/be/excluded
+ * DenyPath /some/other/path/excluded
+ *
+ * # Deny everything from *.example.com and example.com
+ * Domain example.com
+ * DenyPath .*
+ *
+ * Domain example.org
+ * DenyPathQuery /resource/.*?action=exclude
+ * </pre>
+ *
+ * <code>Host</code> rules are evaluated before <code>Domain</code> rules. For
+ * <code>Host</code> rules the entire host name of a URL must match while the
+ * domain names in <code>Domain</code> rules are considered as matches if the
+ * domain is a suffix of the host name (consisting of complete host name
parts).
+ * Shorter domain suffixes are checked first, a single dot
+ * "<code>.</code>" as "domain name" can be used to specify
+ * global rules applied to every URL.
+ *
+ * E.g., for "www.example.com" the rules given above are looked up in the
+ * following order:
+ * <ol>
+ * <li>check "www.example.com" whether host-based rules exist and whether one
of
+ * them matches</li>
+ * <li>check "www.example.com" for domain-based rules</li>
+ * <li>check "example.com" for domain-based rules</li>
+ * <li>check "com" for domain-based rules</li>
+ * <li>check for global rules ("<code>Domain .</code>")</li>
+ * </ol>
+ * The first matching rule will reject the URL and no further rules are
checked.
+ * If no rule matches the URL is accepted. URLs without a host name (e.g.,
+ * <code>file:/path/file.txt</code> are checked for global rules only. URLs
+ * which fail to be parsed as {@link java.net.URL} are always rejected.
+ *
+ * For rules either the URL path (<code>DenyPath</code>) or path and query
+ * (<code>DenyPathQuery</code>) are checked whether the given
+ * {@link java.util.regex Java Regular expression} is found (see
+ * {@link java.util.regex.Matcher#find()}) in the URL path (and query).
+ *
+ * Rules are applied in the order of their definition. For better performance,
+ * regular expressions which are simpler/faster or match more URLs should be
+ * defined earlier.
+ *
+ * Comments in the rule file start with the <code>#</code> character and reach
+ * until the end of the line.
+ *
+ * The rules file is defined via the property <code>urlfilter.fast.file</code>,
+ * the default name is <code>fast-urlfilter.txt</code>.
