HTTP To TCP Conversion

Hi, I am planning to use Nginx as a webserver to the front end of my susbcriber tasks (1:N, 1 Rest Server for N Subscriber Tasks). The communication between the Nginx and my tasks would be over TCP. So, when the Nginx receives the HTTP messages, it will parse the message and then put to those

COAP Reverse Proxy

Re: SSL Offloading in UDP load

Thanks Maxim. I am looking for a scenario to load balance the LWM2M server (my backend servers would be LWM2M Servers). I am thinking of using the Nginx UDP loadbalancer for this. Now, if you look at the LW2M stack, it has DTLS over UDP. So, I was thinking if I could offload the DTLS traffic here.

Re: Compression with Caching

Thanks I am not sure why we don't first compress and then store the same in the cache. In this way, we don't have to compress the content each time (if the client is asking for a gzipped content) before sending to client. I am not able to understand why it is currently designed thisway,

Nginx with NO SSL offload

Hi All, Is there way I configure Nginx not to do SSL offload, i.e Nginx should receive the HTTPS traffic (by listening on port 443) and forward the same to the backend server without doing an offload. I think I can do this if I setup my Nginx in TCP mode (using the third party module tcp proxy).

Re: Memcached

Thank you. I think agentzh's memc-nginx-module module comes with little more features than the default ngx_http_memcached_module which Valentin suggested. If I download nginx, I see the ngx_http_memcached_module. So, it is not a third party module. I will evaluate and see which one to use.

Thank you. But, my question is when we are allocating a pool of more than one page size why are we putting the max value as one page size and then further leading to memory allocation. Posted at Nginx Forum: http://forum.nginx.org/read.php?2,249161,249189#msg-249189

Re: Memory Pool

Thank you for the reply. I know it is simple. But, will we not get more performance benefit if we create the pools before hand. Say I will create a memory pool for the connections (for example say with 4000 entries). Everytime I need one, I will go and get it from that pool and when I free it, I

memory pool allocation

Suppose, I am allocating a pool of greater than 4k(page size). Say for example I am calling the function ngx_create_pool with 8096. But, this function will set the max as 4095 even if it has allocated 8K. Not sure, why is it being done like this. p-max = (size NGX_MAX_ALLOC_FROM_POOL) ? size
