It's harder to write safe code for persistent environments than it is for CGI. There's no question about that. Unfortunately, you'll have to get used to it, because nearly all web code written now is for persistent environments. The performance benefit is big enough to outweigh the danger. Keep in mind that the danger here is no greater than it would be for someone using FastCGI, Java servlets, etc. If you create persistent variables (i.e. package variables declared without "my") you will have to be responsible for clearing them when you want them cleared. - Perrin
