yeah, don't let them upload anything over the limit. Your logic is flawed. You read whatever they're throwing at you, even if it is a 100GB, and then you check the size, that's beyond crazy. Look into the HTTP spec, and further into CGI.pm, and even CGI::Safe and check for that before accepting anything. Doing this one file at a time is logically the easiest way to do it.

Also, this is by no means a perl problem. You need to think a little harder when naming nodes (asking questions). There is a tutorial on asking questions in our Tutorials section. One of the most important things to keep in mind is reusability.

How does your question benefit the community as well as you? By having a meaningfull node title so that others with the same question can find it quickly and easily ... perl question says nothing about your question.
