@semiosis I finally understand what is going on here by reading the [mod_rewrite](http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule) documentation.  That's cool.  I didn't know that one could `ProxyPass` like that.

One thing that sort of pops out at me is `^/(.*)$`.  Since you don't have a forward slash in `http://127.0.0.1:8080%{REQUEST_URI}` shouldn't it actually look something like this?

    RewriteRule ^(.*)$ http://127.0.0.1:8080%{REQUEST_URI} [P,QSA]
