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

[Valery Kholodkov]

Could you please show the code where you install the handler?

I have previously looked at how NGX_AGAIN is handled in the nginx source, and its along the lines of if ngx_http_read_client_request_body returns anything other than NGX_OK, return that from the module, otherwise return NGX_DONE. The problem is when I do this, my module is never called again.

Is this supposed to be expected behavior?
