hi ,
I want to get data from memcached , if the data is gzipped , I also need to gunzip it , I will check memcached flag to judge if it is gzipped . I use memc-nginx-module to get memcached data And I want to return value and flag , but ngx_location_capture only return value without flag . How can I get flag ? This is my nginx.conf . Thank you , very much
location ^~ /api/2/topic/nodejs {

local args = ngx.req.get_uri_args();
local resp = ngx.location.capture( '/mem' , { share_all_vars = true });
if resp.status == 200 then
local encoding = ngx.var.flag;
if encoding == 2 then
local zlib = 'zlib';
local stream = zlib.inflate();
local jsonp = ngx.location.capture( '/mem2' , { args = args ,body = stream(resp.body) } );
ngx.say(jsonp.body);

local jsonp = ngx.location.capture('/mem2' , {args = args , body = resp.body});
ngx.say(jsonp.body);
end
