Location_Capture_By_Lua and Reverse Proxy Cache

[shubham s.]

Hi,

Was trying to get hold of the response recieved through upstream server
or through nginx cache . However found that thier's no cache hit when
doing this way .

for brevity just posting the relevant code : looks like for something
out there through which cache is ignored : also the headers out of
Passenger_backed are not returned through the conetnt_by_lua stuff.

location / {

content_by_lua '
     local res = ngx.location.capture(
                "/passenger_backend",
                { method = ngx.HTTP_POST, body = ngx.var.request_body})
     ngx.header["X-My-Header"] = "blah blah"
     ngx.log(ngx.CRIT,"Inside Content : " , "hello")
     ngx.say(res.body)
      ';
    }

======

 location /passenger_backend {
      proxy_pass http://web_units;
      proxy_cache small;
      proxy_cache_methods POST;
      proxy_cache_key "$request_uri|$request_body";
      client_max_body_size 500M;
open_file_cache max=200000 inactive=50s;
open_file_cache_valid 50s;
