Hi all,

I'm currently developing a rails app that required to do cross side 
scripting with ajax. I've been google around and found this<https://gist.github.com/206529>rack middleware that used rack on doing proxy. However I have no idea on 
how to use it in my app. Please help, I'm using Rails 3.2.3. Thanks!

It sounds like you probably want CORS though, not a proxy.

Hi, thanks for your reply.

According to this source<https://developer.mozilla.org/en/HTTP_access_control>, 
CORS will required the targeted domain (http://bar.other in this example) 
to response with the "Access-Control-Allow-Origin".

This is the reason I'm not using CORS, because the targeted domain is not 
belong to me, I've no way to add the "Access-Control-Allow-Origin" header 
on its server. Correct me if I'm wrong.

I suggest you proxy only the routes you need.

Yes, that's what I wanted to do with the rack middleware. So how to use it?
