I was sure something was possible too, two days later I'm starting to
believe Joshua now. The problem seems to be having the environment
variable in the regex side of the rewritecond statement.
Thanks for the reply

I don't believe that's true. I have the following rewrite to remove a
prefix from the REMOTE_USER variable:
RewriteCond %{LA-U:REMOTE_USER} ^EXT_(.*)$
RewriteRule .* - [env=RU:%1]
and:
RewriteRule ^/$ http://%{SERVER_NAME}/site/ [R]
I haven't got a spare server to play around with at the moment, but I'm
sure something is possible. Is it just a case of it doesn't like the
environment variable on the RHS argument?
As someone else asked, have you enabled the RewriteLog?
HTH,
Neil.
