lsapi upstream module
This ticket is to feel out the demand/support for an lsapi module in nginx.
LSAPI  was developed by LiteSpeed Technologies but is not to be confused with the LiteSpeed webserver itself. LSAPI is a light-weight binary transport to facilitate communication between frontend servers (e.g. nginx) and backend application servers (e.g. PHP or Ruby).
LSAPI hash been shown to be a better-performing option than a highly-tuned FastCGI configuration, all other things being equal; with something around 10-20% improvement over PHP-FPM and 40%+ in the case of Ruby.
The LSAPI protocol code is open source under the BSD-license, and as such there should be no license conflict. Like FastCGI/FPM, LSAPI is now in mainstream PHP as of version 5.3. There are other advantages to LSAPI such as .htaccess support, but they are secondary incentives to the performance metric.
The LSAPI code can be found at .
