I haven't looked at this in detail, but it is my understanding that
mod_rewrite can't provide this, because it doesn't know all the
processing that apache is going to do on the url. But you can use the
-F or -U checks to have mod_rewrite run through all the apache
processing.

Thanks for the reply.

What do the -F and -U flags do for RewriteCond? I read (and re-read) the
documentation but I am a smidge unclear on it.

To quote: (from
<http://httpd.apache.org/docs/mod/mod_rewrite.html#RewriteCond>):

""""
'-F' (is existing file via subrequest)
Checks if TestString is a valid file and accessible via all the server's
currently-configured access controls for that path.
""""

So, the string is checked against the apache configuration to see if it
comes up with a valid file? Even my explanation doesn't make sense to me.

Any clarification would be good; in the meantime, I will muck with it to
see if I can get it to work.

Later...
