Sysoev: We're planning JavaScript configurations, using JavaScript in [an] Nginx configuration. We plan to be more efficient on these [configurations], and we plan to develop a flexible application platform. You can use JavaScript snippets inside configurations to allow more flexible handling of requests, to filter responses, to modify responses. Also, eventually, JavaScript can be used as [an] application language for Nginx. Currently we have only Perl and Lua [supported in Nginx]. Perl is our own model, and Lua is a third-party model.
