 147 =head1 NAME
 148
 149 check-url-quick.pl - Check URLs from biblio records
 150
 151 =head1 USAGE
 152
 153 =over
 154
 155 =item check-url-quick [--verbose|--help|--html] [--tags 310 856] [--host=http://default.tld]
 156 [--host-intranet]
 157
 158 Scan all URLs found by default in 856$u of bib records and display if resources
 159 are available or not. HTTP requests are sent in parallel for efficiency, and
 160 speed.  This script replaces check-url.pl script.

 162 =back
 163
 164 =head1 PARAMETERS
 165
 166 =over
 167
 168 =item B<--host=http://default.tld>
 169
 170 Server host used when URL doesn't have one, ie doesn't begin with 'http:'.
 171 For example, if --host=http://www.mylib.com, then when 856$u contains
 172 'img/image.jpg', the url checked is: http://www.mylib.com/image.jpg'.
 173
 174 =item B<--tags>
 175
 176 Tags containing URLs in $u subfields. If not provided, 856 tag is checked. Multiple tags can be specified, for example:
 177
 178  check-url-quick.pl --tags 310 410 856
 179
 180 =item B<--verbose|-v>
 181
 182 Outputs both successful and failed URLs.
 183
 184 =item B<--html>
 185
 186 Formats output in HTML. The result can be redirected to a file
 187 accessible by http. This way, it's possible to link directly to biblio
 188 record in edit mode. With this parameter B<--host-intranet> is required.
 189
 190 =item B<--host-intranet=http://koha-pro.tld>
 191
 192 Server host used to link to biblio record editing page in Koha intranet
 193 interface.
 194
 195 =item B<--timeout=10>
 196
 197 Timeout for fetching URLs. By default 10 seconds.
 198
 199 =item B<--maxconn=1000>
 200
 201 Number of simulaneous HTTP requests. By default 200 connexions.
 202
 203 =item B<--help|-h>
 204
 205 Print this help page.
