rack, rack-mount, and grape

[ericgj]

I just started looking at Grape. It strikes me as an extremely clean framework built on rack (and rack-mount for routing), and therefore may be good to look at for this code reading.

Rack-mount itself is interesting too. It mentions it ...supports Rack’s X-Cascade convention to continue trying routes if the response returns pass. But I don't see that documented anywhere, for instance in the interface spec nor in Rack::Cascade where I'd expect it. Anyone know where to look for info on this, is it a convention only rack-mount uses or is it used more widely?

@ericgj I used to a quick look Grape as well, and I impressed about good quality codes, specs, and its simplicity API as well.

Anyone know where to look for info on this, is it a convention only rack-mount uses or is it used more widely?

I can't find it as well, but there is a short introduction section of Sinatra: Up and Running on pg 78-82 that talks about Middleware Chain, Cascade, and Rack::Mount.
