OT: Restrict Access to page

If the redirection is the last thing in the script (which it often is) then
you won't notice the 'essential' character of that exit; function. But -
embed the redirection in the middle of the script and you'll bada bing right
out the window....

Without exit, there's a danger that the rest of the script will be
displayed. Using exit guarantees that the script finishes there.

Relative links work fine, but they're frowned upon by the HTTP police.

The KISS principle today is often used by software developers,
meaning the software should be designed in the simplest way,
avoiding creeping featurism.

How crucial is the exit; line, David? I have to admit I haven't been
using it in my code. And I've been using a relative link too - time
for some search and replaces I think.

This method works fine.

Yes, I thought of that, too, but it was so much less of a challenge.... 8)

The other option, if this is a set of pages in a single directory on an
Apache server, is to restrict access to the directory using .htaccess and
.htpasswd.

Thanks, David. I'll give that a try. I'm not sure why it's making things
hang, but when going to one of those pages, I get a timeout error....
