I'm trying to do something that seems pretty simple with Apache, and I'm pulling my hair out over it... I'm just trying to get a sub-sub-dir "/a/b/c" to be accessible via a sub-dir "/a/c" within an existing VirtualHost. I've tried rewrite rules, proxy rules, locations, nothing has worked, so I assume I'm screwing up syntax somehow. For example: RewriteRule ^/a/c(.*) /a/b/c$1 [R] This comes up as a 404 error. Any idea why?
