How to handle NGX_AGAIN returned by ngx_http_read_client_request_body() within handler module?

[CarlWang]

Thanks for your help.

I just followed Emiller's Guide To Nginx Module Development and build my
Non-proxying Handler. I'm not quite sure which phase is the handler
function running in. Maybe NGX_HTTP_ACCESS_PHASE or
NGX_HTTP_CONTENT_PHASE.
