In order to help debuging the problem, you can turn on LSWS debug log by setting debug level to "HIGH" from the web admin interface.

What language is being used? Are you using any Fast CGI SDK or implementing the Fast CGI protocol stack yourself?

Thanks for your response. As detailed in http://www.fastcgi.com/devkit/doc/fcgi-spec.html#S5.5, FCGI_END_REQUEST should only be used at the end of the response. As the response consists of multiple parts (with a second or two delay between each one), there is only one logical request to the FCGI communications layer.

Apache handles this by turning off buffering if the script issues a complete HTTP compliant header (including the response code line) - see http://httpd.apache.org/docs/misc/FA...ml#nph-scripts.

FYI, I'm using Perl's FCGI module.
