advice on a Rev-plus-internet setup (off-topic)

[Nicolas Cueto]

Many thanks to Viktoras and Len for the server side "relay"
explanation.

I can now use Rev to connect with a MySQL database stored on my
web-host's server thru a php relay-script that is also on the same
server.

One other thing, now. The issue of security has been brought up. For
now,
my solution has been to place my server-side php relay-scripts in a
password
protected folder. This way, when my Rev stack calls the php
relay-script, I
include the user name and password for that folder in the url.

Is that sufficient? Or, what's the other avenue I should now be
following?

Again, many thanks for both the help and patience.

Cheers,

Nicolas Cueto
