HI, I’ve some links to permit the visitor to download documents (zip files) from the server, I need to trigger if the file doesn’t exist to send him an alert but seems that the function getUrl() can’t have listeners or handlers.

Anybody knows how can I do it ?

Thanks and have a nice day :sigh:

The “easiest” is using sockets, but that might get heavy on the server if you have heavy traffic on your site. another way to do this is setting a timeout period.  
Make an object that will load the target, and check to see if the target is loading (by checking if the totalBytesLoaded is greater than 4). If after X seconds (usually 4-7) it’s still 4 or lower, than it is not loading, and you can do whatever it is you want to do in that case.

an easy way to do this would be to make a php or asp download handler script. Therefore you could track how many times the file has been downloaded as well and store it in a database.

The way you would do this is do something like:

download.php?d=http://dljafjd.com/file.zip

then pass that string in the php file and redirect when your finished with the script. if the file doesnt exist it could take you to a “file not found” page.
