provide way to modify req/res

[drewzboto]

Can you be more specific? Is there a reason you can't do this with standard server middleware?

[atian25]

yes, such as :

• the real server don't allow cross-domain, so we wan't to modify res.headers
• we are develop a hybrid app, the android code will intercept xhr request then add some sign msg
• or sometime we just wan't to redirect to a local json just for debug.
