Iis|iis IIS primarily integrates the three Web server features of the Windows NT Server network operating system, which transmits data through the standard HTTP protocol, and all IIS services (WWW,FTP and SMTP) are single process multithreaded architectures. Used to optimize performance.
The client/server protocol used by WWW is HTTP, which means that customers and servers need to interact to perform specific tasks such as clicking a hyperlink on an HTML page on the Web, resulting in an existing page being replaced by a new page that IIS passes through windows Sockets to support HTTP, and current IIS supports the HTTP 1.1 version.

FTP is the protocol that is used to transfer files between two computers on a TCP/IP network, and IIS supports FTP through Windows Sockets, although fewer people are now using the FTP user interface, but this protocol will still be used to transfer files over a period of time. Because it has been widely accepted by Internet users, FTP uses TCP as a transport protocol for all communications and exchanges between its clients and servers, while IIS deals with TCP with Windows Sockets.

All standard Internet services, such as FTP and HTTP, are located in a process called inetinfo (Internet Information Services application,internet Information Service application). In addition to these Internet services, the process includes a shared thread pool, caching, logging, and SNMP services.

HTTP and FTP run in the same process, so they can share data in the cache, such as file handles, account information, and log file data.

You can use records to track those users who are accessing your node, and control when nodes can be accessed, tracking users can help determine security and performance issues, and trace information can be logged directly to the log file, which can be processed offline for better performance, and can also be recorded in the database. For a dynamic evaluation.
