Module connecting outside

By checking the ngx_http_upstream I don't see any kind of handling in case
the ngx_ssl_handshake returns NGX_ERROR, I am trying to catch this error in
order to handle network outages and subsequent reconnections attempts from
my module. Do you think this could be a good way to trigger reconnection
timer? At the moment I am handling reconnections also in the read and write
events when if(wev->timedout || c->error || c->close).
