Description

It would be nice to have an option to disable fcgi buffering.

Note:

  • fastcgi_max_temp_file_size supports '0' value;
  • fastcgi_buffer_size throws error if fcgi header is bigger than specified value.

Just for the record, the following options already exists:

  • scgi_buffering;
  • uwsgi_buffering;
  • proxy_buffering;

I'm second to vote about this ticket.

Please note, without this option it is impossible to implement several important COMET techniques.

For example HTML5 EventSource? or other methods like hidden iframe.

In Event streaming it is common to flush small buffers to the stream, so flushing, at least at the level of FastCGI record boundaries would very useful.

Note, other web servers support such an option, for example Apache has -flush option, lighttpd does this by default.

I would even consider this as a bug.

Thanks.
