Here are some details about Microsoft's next web server, Internet Information Services 7 (IIS7) which is planned for late 2006. The update will integrate ASP.NET and will turn many core features into optional modules.
The software architect said the unification process meant many ASP.NET concepts such as HTTP pipelines, modules and XML config files would be built into IIS7.
In addition, he said, creating modules out of IIS features would reduce the amount of code running live on a system, minimising the available footprint for hackers to attack. "From a security standpoint, this is a whole new realm for IIS," he said.
It is said that the modular approach to ISS will boost performance, security and ease of patch management. More info about new features in IIS7 can be found at ZDNet
