|
|
|
|
<P>IIS defines a basic functionality that you can use to build Web applications. Active Server Pages (ASP) and other Microsoft technologies have extended this basic functionality to create a rich environment for application development. The basic server functionality is exposed through the Internet Server Application Programmer Interface (ISAPI). ISAPI is described in detail in the Microsoft Platform SDK.</P>
|
|
|
|
<P>The core functions which IIS provides include:
|
|
|
|
<UL type=disc>
|
|
<LI>Establishing and maintaining HTTP connections.</li>
|
|
|
|
<LI>Reading HTTP requests and writing HTTP responses.</li>
|
|
|
|
<LI>Modifying HTTP headers.</li>
|
|
|
|
<LI>Obtaining client certificate information.</li>
|
|
|
|
<LI>Managing asynchronous connections.</li>
|
|
|
|
<LI>Mapping Uniform Resource Locators (URLs) to physical paths.</li>
|
|
|
|
<LI>Managing and running applications.</li>
|
|
|
|
<LI>Transmitting files.</li>
|
|
</UL>
|
|
|
|
<P>ASP extends this functionality by providing a link to the COM architecture and thus the other participants in Windows DNA. Similarly, you can extend the IIS architecture by defining a custom set of functions using ISAPI. The relationship between the IIS core functionality, ASP, and extended architectures is depicted in the following graphic:</P>
