RE: Simple Session?

Besides the other good suggestions, if you need a cryptographically strong session key, you can use what Apache::Session uses:

use MD5;

sub generate_id {
    return substr(MD5->hexhash(time(). {}. rand(). $$. 'blah'), 0, 16)
+;
}

Says merlyn: `sub generate_id { return substr(MD5->hexhash(time(). {}. rand(). $$. 'blah'), 0, 1 +6); }` [download] That `{}` seems like something of an oddity. I guess they threw it in on the theory that it couldn't hurt. (Part of me wants to say that `[]` would accomplish the same purpose, but with less memory. No doubt tye will not consider this funny. `:-)` )	[reply] [d/l]
