FastCGI: Persistent Applications for Your Web Server

FastCGI allows Apache to run and manage persistent CGI-like scripts, overcoming CGI's worst shortcomings.

My example script doesn't tackle many of the tasks at which FastCGI excels: persistent database connections, format translation (e.g., SGML to HTML) or providing common HTML page headers and footers. At the site I manage, I use FastCGI to do all these things and more.

I've found that a FastCGI application can perform its duties, including multiple SQL queries, and deliver a page on the fly only slightly slower than the server can deliver static documents. On a 10Mbps LAN connection the speed difference is perceptible, but just barely, and only if I'm looking for it. Over a 128Kbps or slower connection, I notice no difference.

I still use CGI to perform simple, infrequently needed tasks. A CGI script doesn't hog system resources for very long. For complex, frequently invoked tasks, FastCGI provides a great combination of flexibility and speed.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
