Apache is the most popular and powerful web server software available today. All Virtual Server HTTP service is now provided by a customized version of the Apache 1.3 Web Server.

• Upgrading Your Virtual Server Apache

We have made some modifications to Apache to extend its flexibility and power. Performance enhancements include more efficient handling of HTTP requests, improved protection against process loading, and better error recovery. These improvements have reduced CPU load balances up to three times on many of the Virtual Server host machines. That directly translates to better performance from your Virtual Server.

Some of the most notable features of your Virtual Server HTTP service include the following.

• Virtual Hosting
  This feature allows you to support multiple domain names that each resolve to their own unique subdirectories on a single Virtual Server. In other words, you can host "domain1.com" and "domain2.com" on the same Virtual Server, each with its own domain name and unique site content.

• Dynamic Apache Module Support
  This support provides you with the ability to extend the features and capabilities of Apache by adding the specific modules you need, when you need them. User-installable dynamic modules include improved web server functionality, integrated support for web server add-ons, and more. The APXS (APache eXtenSion) tool is also supported. APXS allows you to compile and link your own dynamic shared object (DSO) modules.
