You can't do this with iptables.

You're confusing the application layer(7) with the network layer (3).
iptables works at layer 3 and is thus not aware of filesystem folders or
web directories.

You'll need to use http redirection to accomplish what you apparently
desire above, either with an http proxy or http server.
