2008年11月2日 · SCGI is a language-neutral means of connecting a front-end web server and a web application. WSGI is a Python-specific interface standard for web applications. Though they both have roots in CGI, they're rather different in scope and you could indeed quite reasonably use both at once, for example having a mod_scgi on the webserver talk to a ...

2011年5月14日 · You need an SCGI client that runs as deamon, and that accepts socket connections on an agreed port (4000 or 5000 seem common). SCGI is no different than FastCGI. Each language would require its own daemon, you can run multiple.

2010年10月14日 · SCGI (Simple Common Gateway Interface - a simpler FastCGI) AJP (Apache JServ Protocol - a Java FastCGI) mod_python (runs pre-loaded code per request - uses lots of RAM) CGI (Common Gateway Interface, starts a process per request - slow)

2016年2月18日 · The uwsgi (all lowercase) protocol is derived from SCGI but with binary string length representations and a 4-byte header that includes the size of the var block (16 bit length) and a couple of general-purpose bytes.

2010年3月28日 · FastCGI, SCGI, and AJP run the web app as a separate process (daemon), and pass messages between the web server and it. mod_python is used to embed Python code into the httpd process during any of the request phases. mod_wsgi can run Python code in either daemon or embedded mode.

2012年1月19日 · Major web frameworks (such as Django, Pyramid, Rails, etc) are often run as persistent servers, with a separate web server like nginx serving as a frontend. The web server connects via a protocol like FastCGI or SCGI: browser --[http]--> nginx --[fastcgi]--> flup -> django

2015年4月27日 · Is there any way to configure mod_scgi to be case insensitive? I searched the lighttpd docs and configurations but couldn't find a thing. The source code of mod_scgi is ok to read and understand, but I didn't find a line where the CGI-URI is handlend or compared or so. Thanks for any hints!

Note that with using WebSockets, you no longer need CGI, FastCGI or SCGI protocols for connecting the web server with the application back end. Just implement a TCP listener in your application (for mod_websocket to connect to) and use the socket for asynchronous I/O.

Well, The hexadecimal <31 32 3a 68 65 6c 6c 6f 20 77 6f 72 6c 64 21> in ASCII is "12:hello world!" (no quotes) and the lenght is 12 (hello world!)
