Hi,

I got the problem that one of my servlets creates a very big pdf from database, which can take several minutes. To not waist ressources, I want to detect if the user pressed the stop button. The only way to do that, as far as I know, is to stream a space or a bit and check if there is an IOException. So, does a pdf file ignore leading spaces or bits at the beginning or is it impossible to check if the user pressed the stop button?
