<tt><font size="-1">Hi,<br>
<br>
I have problem with nginx and memcached responses such as
text/html or <br>
application/json and </font><font size="-1">I will be glad for
any help</font><font size="-1">. Thanks.<br>
<br>
My idea is:<br>
-First request on nginx server (reverse proxy memcached server)<br>
-Try if I have memcached response (memcached run on same server
as <br>
nginx)<br>
-If not pass request to application server<br>
-Application server makes response<br>
-Stores response in to memcached<br>
-And for next same request nginx hit response from memcached and
return <br>
to client.<br>
<br>
But the problem is, when the application server stores response
to <br>
memcached (data in memcached are stored good and corectly) and
NGINX hit <br>
the request in memcached, but return totaly wrong hashed
content.<br>
<br>
For example:<br>
First request, ngingx didnt find response in memcached, pass to
<br>
application server, and here is response ... good and correct
JSON.<br>
------- Headers<br>

<br>
But for the second request, when NGINX find response in
memcached, NGINX <br>
serves response totaly wrong.<br>
