mod_cgi

mod_cgi is a module for the Apache web server that allows it to run external programs, called CGI scripts, to generate dynamic web content. When a user requests a specific page, mod_cgi executes the script, which can produce customized data, display forms, or process user input. This enables websites to deliver interactive and personalized content beyond static pages. Essentially, mod_cgi acts as a bridge, enabling the server to communicate with external code to make websites more flexible and responsive.
