The `fcgi` package is the FastCGI Developer's Kit: headers, libraries, examples, language integration material, and the `cgi-fcgi` tool used to develop and test FastCGI applications. ### Project history Open Market published the FastCGI 1.0 specification on April 29, 1996. The spec defines the interface between FastCGI applications and supporting web servers from the application's perspective. The Developer's Kit dates to the same 1996 Open Market codebase. The current FastCGI-Archives repository preserves a fork of the original FastCGI SDK after the historical FastCGI.com site disappeared. ### Adoption history FastCGI was adopted because it offered CGI's language-agnostic deployment model without forcing every request to spawn a new process. The official docs include integration material for Perl, Tcl, and Java as well as C library documentation. Its long-term package-manager role is legacy infrastructure: modern web stacks often hide FastCGI behind application servers or language-specific process managers, but `fcgi` remains the small C SDK and bridge tool that many systems keep available for compatibility. ### How it is used Developers use the library to write FastCGI applications that accept requests over a listening socket and exchange FastCGI records with a web server. The SDK includes examples, headers, `libfcgi`, and language-specific documentation. The `cgi-fcgi` command is useful for development and testing because it can bridge CGI-style invocation and FastCGI applications, including when a web server lacks direct FastCGI support. ### Why package nerds care FastCGI is package-nerd archaeology that still matters: a 1990s web protocol whose ABI, headers, and helper binary continue to be packaged because web servers, wrappers, and legacy applications still know how to speak it. The package is also the dependency behind tools like fcgiwrap, making it part of the compatibility layer that lets old CGI programs survive behind newer web-server configurations. ### Timeline - 1996: Open Market published FastCGI specification 1.0. - 1996: The FastCGI Developer's Kit documented libraries, examples, language integrations, and `cgi-fcgi`. - 2016: The FastCGI-Archives/fcgi2 GitHub repository was created to preserve the SDK after the original FastCGI.com material moved offline. ### Related projects - CGI is the predecessor interface that FastCGI extends. - fcgiwrap, spawn-fcgi, web-server FastCGI modules, and language runtimes such as PHP-FPM are part of the surrounding FastCGI ecosystem. ### Sources -
