Can't add a pass before or after the first.

Created by: ghost

Using before or after and providing the name of the first pass, the falsy check here: https://github.com/nodejitsu/node-http-proxy/blob/master/lib/http-proxy/index.js#L146 will always indicate that the name could not be found.

Instead this should read something like if(i === false).

The same issue is present in after.
