Thank you for your help; I have taken your advice on the environment
variables and used this:

RewriteRule ^a.php$ b.php [E=foo:bar]
RewriteCond %{ENV:foo} !="bar"
RewriteRule ^b.php$ - [F]

However requests to a.php are still returning a 403. Could you tell me
if I'm missing the point with the way these variables work?

Thank you
