Keepalive not working with upstream tcp server

I am setting u->keepalive = 1 in my module too, but let me double check that though.


Meanwhile , is the keepalive done by http_upstream_keepalive_module ? Is it included by default or do I need to compile explicitly include that module.  I don't see the code going through that module in my request flow.

Looks like you did something wrong in you module.  Note that 
memcached module explicitly sets u->keepalive when it's ok to keep 
a connection alive.
