The ngx_drizzle module (and ngx_postgres module) does not support the
standard upstream's "subrequest_in_memory" feature. But you can always
capture the subrequest's response in memory yourself in your own Nginx
output filters, just like how ngx_lua module's ngx.location.capture()
Lua API captures the response of *any* nginx subrequest:
http://wiki.nginx.org/HttpLuaModule#ngx.location.capture
BTW, I'm cc'ing the openresty-en mailing list:
https://groups.google.com/group/openresty-en And you're highly
recommended to discuss such things there :)
Thanks!
