The domains in the hosts file must be 2 or 3 segment domains, such as "yahoo.com" and "finance.yahoo.com". If the length of the last 2 segments is less than 7, such as "com.pl", then it is treated as one segment, so domains like "xxx.xxx.com.pl" are also valid in the hosts file.</p> <p>Each line of the hosts file has the following format:<br> [rootDomain][space][regex for domain prefix before rootDomain][space][regex for the whole url without "http(s)://"]<br> The first part [rootDomain] is required and the others are optional. regex is java-grammar regular expression. If the second regex is used, it is recommended to merge the first regex to the second one for performance.</p> </div> </body> </html>
