First, let's take a look at IIS. IIS Server is short for Internet Information Server. It is a WEB Server promoted by Microsoft. Currently, the commonly used version is IIS 6 in Windows2003 or IIS 5 earlier.
IIS Server and Window NT Server are fully integrated. Therefore, you can use the built-in security features of Windows NT Server and NTFS (NT File System, NT File System, build powerful, flexible, and secure Internet and Intranet sites.
In earlier versions of IIS servers, developers needed to write ISAPI extensions/filters to expand server functions. Besides being difficult to write, ISAPI is also very limited in terms of how to access the server and allow developers to customize.
The new IIS server brings many benefits:
1) You can now use ASP. NET form authentication, members/roles, and any other features for all requests (such as. htm,. php, And. jsp files) on the IIS server.
2) You can easily rewrite the URL of any web request or modify the request in a variety of interesting ways.
3) You can use VB or C # to replace or expand any existing IIS server features (for example, you can remove the built-in directory list module and access your own modules ).
This gives. NET developers an infinite number of expansion opportunities. For more information about IIS servers, see here.
