Automatically checks links from more that 50 file hosts, the script is checking the links in bulk when ever possible, that means maximum speed and low bandwidth.
When the check was made in bulk the script can check hundreds of links in a split of a second (300 links in 0.1 - 0.3 sec and 900 links in 0.5 sec on my ADSL connection). When the check was not made in bulk the speed is low and the use of bandwidth is increased because for each link check the script is downloading the checked page in the background.
