No it isn't.  It's a question about a task, for which one possible
solution might be using conditions in mod_rewrite.

If you're on a modern operating system such as Linux, you may have been
doing a lot of work for nothing.  The kind of scheme you describe is only
really necessary if your filesystem uses linear search.  Putting your
data on an appropriate filesystem solves that instantly.

Stated like that, mod_alias appears to be a simpler (and probably faster)
solution than mod_rewrite.  But I'm not sure you really sure how to
do it in a single regexp: httpd.conf is not Perl (unless ....).
The basic syntax would be the same with AliasMatch as with RewriteRule.

Oh, and even in Perl, a single regexp is probably slower than two simple
ones here, unless you can do it without /e.
