Just some random nginx config trying to give myself a big picture and
think aloud:

location /foo {
# XXX search in-process cache...
eval $val {
set $memcached_key $arg_foo;
memcaced_pass some.host:11211; # tokyotyrant, memcached, or etc
error_page 404 = @bar;
};
more_set_input_headers 'X-My-Header: $val';
# XXX put $val into in-process cache...
proxy_pass 'http://blah.blah.blah';
}
location @bar {
echo "";
}

The "# XXX" part is something that is missing atm :P

To be honest, I've also been thinking about building such a module
myself. Will you join the development? (Even though I'm still
polishing ngx_drizzle and ngx_oracle with chaoslawful right now ;))

Cheers,
