What is an IIS server module & why would I use one?

An IIS server module is software that resides on and directly interacts with Microsoft's Internet Information Services (IIS) Web server on Windows NT, 2000, XP, and 2003 systems to extend its functionality (similar to the relationship between ASP.NET components and ASP.NET). Our implementation usually is via ISAPI filters and extensions, though we also provide other software solutions.

The unique advantage of an IIS server module is the capability to act upon each request at any point in the request/response life cycle. For repetitive or global tasks involving HTTP requests, this is the most efficient place to get the job done. The wide use of standard Apache modules in the Linux/Unix world shows the benefits of using server modules to enhance Web server functionality. Port80 Software brings that value to the Microsoft IIS space. While we are developing Windows-based software, the success of Apache modules has provided the inspiration for Port80's next-generation IIS server modules.


Do your products handle heavy site traffic?

Yes. We have thoroughly tested our filters against load and stress. We have found them to be free of memory leaks and very stable. We have also tested them with other popular products, especially application servers. However, there is no substitute for trying them out yourself.


What is Port80 Software all about?

Port80 Software develops Microsoft IIS server modules that provide HTTP functionality to businesses of all sizes, governments, NGOs, Fortune 500 companies, educational organizations, hosting service providers and Web-based software companies. Most of our team has been in Web development and software engineering for quite some time. Our names are Thomas, Joe, Allan, Eric, Shannon, Chris, Perry, Alex, Christie, and cast of other visiting characters. We're not a huge company, but we work very hard and have a serious passion for what we do.


Where did the name "Port80 Software" come from?

Port80 is the default port number where a Web server listens for and responds to incoming HTTP requests. Our IIS server modules enhance security, performance and user experience by filtering or augmenting requests as they come into your Web server. Most likely, these requests are coming into your Web server via Port80.
