HTTP requests are sent in parallel for efficiency, and speed. This script replaces check-url.pl script. =back =head1 PARAMETERS =over =item B<--host=http://default.tld> Server host used when URL doesn't have one, ie doesn't begin with 'http:'. For example, if --host=http://www.mylib.com, then when 856$u contains 'img/image.jpg', the url checked is: http://www.mylib.com/image.jpg'. =item B<--tags> Tags containing URLs in $u subfields. If not provided, 856 tag is checked. Multiple tags can be specified, for example: check-url-quick.pl --tags 310 410 856 =item B<--verbose|-v> Outputs both successful and failed URLs. =item B<--html> Formats output in HTML. The result can be redirected to a file accessible by http. This way, it's possible to link directly to biblio record in edit mode. With this parameter B<--host-intranet> is required. =item B<--host-intranet=http://koha-pro.tld> Server host used to link to biblio record editing page in Koha intranet interface. =item B<--timeout=10> Timeout for fetching URLs. By default 10 seconds. =item B<--maxconn=1000> Number of simulaneous HTTP requests. By default 200 connexions. =item B<--help|-h> Print this help page. =back =cut
