Apache httpd serves the majority of domains registered in the world - it's ubiquitous. A fabulous range of facilities and modules provide a huge tailoring scope and occasionally a configuration nightmare.

Apache Tomcat is another web server. Although you find it fronting only a tiny proportion of registered domains, it's often present in the background, hidden behind Apache httpd running on the same server. If you hear "Web" and "Java" , you'll likely find a Tomcat around!

Why two web servers, both from Apache? Httpd is a great web server for handling single pages, and for traditional sites which hava a large number of different pages to be served. By contrast, Tomcat is an application container in which a handful of applications are run and each subsequent requests back to the server results in the same application taking the process a stage further on.

We offer a Linux Web Server cause that covers the installation and maintainace of Apache httpd on Linux systems, and further Linux courses (see the menu to the right) if you wish to learn about the operating system too. If you're using httpd to front Tomcat, or Tomcat on its own, our deploying Apache httpd and Tomcat course will be the one for you.

If you've a group of three or more delegates who wish to learn about these web servers at the same time, a Specially Run Courses course can be arranged, and for larger groups we can also run a Private Courses course at your offices. Such courses are tailored to meet your requirements - please contact us to discuss the detail of what you need.

We use Apache web servers on this site that you're visiting at the moment, and on our in house systems and other sites too. Some of these are quite large sites - www.wellho.net handles dozens of page requests every minute from its anthology of 8000 pages, some of which are true html files, and others are PHP, Perl, Python and Tcl, backed up by MySQL databases. Apache really does provide poweful servers!
