Memcached/JSONP

[Peter Leonov]

Hi, Dylan,

Nginx has a great SSI module. Try it to wrap like in this simple trick:

/wrap.jsonp?some_key_in_memcache

In wrap.jsonp:
window.processJSONP(<!--# include virtual="/memc/$args" -->)

And call this wraper instead of direct src.

Am thinking, it could work.
