PHP form POST question - PHP

When you access /foo, the server will redirect the client to /foo/ (because
it is a directory). At the redirected page, the post data will not be sent
again by the browser thus there are no _POST values.

Try using action="/foo/". That may work.

If you do a post to just the domain name apache does a redirect to /foo/index.php
losing the post info.

Yes, /foo/ does work.

The explanation makes sense.

Bugger! All that time spent banging my head against the wall. :-)

Thanks!
