-----------------------------
Hi [~jpe...@apache.org],
The timeout should be 0 if we turn on SO_LINGER option as we are using
non-blocking socket. I have tried a non-zero timeout, but the setsockopt
failed.
If we add a new sock option
{code}
static unit32_t const SOCK_OPT_LINGER_ON = 4;
{code}
Then we could configure
{code}
proxy.config.net.sock_option_flag_in
proxy.config.net.sock_option_flag_out
{code}
to make client connection or server connection LINGER for 0 ms by need.
> Add option to support SO_LINGER to origin server

> When install ATS and apache in the same box to do SSL termination. We saw
> port exhaustion, performance drop and request missing through ATS.
> Before migration we are using stunnel to do SSL termination. There were no
> such problem. After investigation we found add SO_LINGER option to origin
> could resolve these problem.
