I know there are about 10 million messages on perlmonks about uploading a file, but I haven't come across one that addresses this issue. I'm basically using the script in the OReiley book CGI Programming. The problem is when someone inputs just the directory instead of a file the browser seems to hang. I've set CGI::MAX_POST to a low value. But that doesn't seem to help. I thought I could check for illegal characters in the file name, but it doesn't solve the problem. Can someone please point me in the right direction. Thanks!
