What is mod Fcgid?

mod_fcgid is a high performance alternative to mod_cgi or mod_cgid, which starts a sufficient number instances of the CGI program to handle concurrent requests, and these programs remain running to handle further incoming requests.

When should I use FastCGI?

FastCGI is a protocol based on the earlier CGI, or common gateway interface, protocol meant to improve performance by not running each request as a separate process. It is used to efficiently interface with a server that processes requests for dynamic content.

What is FastCGI used for?

FastCGI is a programming interface that can speed up Web applications that use the most popular way to have the Web server call an application, the common gateway interface (CGI).

What is Apache FastCGI?

This 3rd party module provides support for the FastCGI protocol to Apache 2. FastCGI is a language independent, scalable, open extension to CGI that provides high performance and persistence without the limitations of server specific APIs.

What is Mod_cgi?

Summary. The module mod_cgi provides for execution of CGI scripts. Any file that has the handler cgi-script will be treated as a CGI script, and run by the server, with its output being returned to the client.

How do I enable FastCGI in Apache?

Installing mod_fastcgi manually

  1. Copy or move the mod_fastcgi distribution directory to /src/modules/fastcgi.
  2. Add the FastCGI module to /src/Configuration.
  3. From the /src directory, reconfigure and rebuild Apache.
  4. Edit the httpd configuration files to enable your FastCGI application(s).
  5. Stop and start the server.

What is difference between CGI and FastCGI?

What makes a difference from CGI is that with FastCGI the running process of the application lasts longer and it is not immediately terminated. After the application finishes processing and returns the output data, the process is not terminated and is being used for processing further requests.

Does PHP use CGI?

cgi is a simply a path where people commonly put their CGI script. Web server are commonly configured by default to fetch CGI scripts from that path. a CGI script can be implemented also in PHP, but all PHP programs are not CGI scripts.

What is CGI Apache?

What is the difference between FastCGI and FPM?

Running PHP as a CGI means that you basically tell your web server the location of the PHP executable file, and the server runs that executable PHP FastCGI Process Manager (PHP-FPM) is an alternative FastCGI daemon for PHP that allows a website to handle strenuous loads.

What is the difference between CGI and FastCGI in PHP?

FastCGI was introduced as a middle ground between the PHP Apache Module and the CGI application. It allows scripts to be executed by an interpreter outside of the web server and includes the security benefits of CGI but doesn’t include any of the inefficiencies of CGI.

What was the need for the development of FastCGI?

The need to develop FastCGI is that Web was arisen by applications’ rapid development and complexity, as well to address the scalability shortcomings of CGI technology. To meet those requirements Open Market introduced FastCGI – a high performance version of the CGI technology with enhanced capabilities.

What happens if a FastCGI request does not complete?

If a FastCGI request does not complete within FcgidBusyTimeout seconds, it will be subject to termination. Because the check is performed at the interval defined by FcgidBusyScanInterval , request handling may be allowed to proceed for a longer period of time.
