[kwlug-disc] Sending array variable over Web/CGI?

[Khalid Baheyeldin]

Nothing wrong with building an array.

The issue here is that the data is in the URL (array or not), and that
means it will be logged in the server's access logs, and crawlers may
follow it, ...etc. It can also reveal things that you may not want to
reveal. An extreme case is login name and password in the URL!

The proper way to avoid all this is to use POST, where the data is not
logged anywhere, and not visible to anyone (if you use SSL).
