What is IIS?
IIS (Internet Information Services) is a web server software developed by Microsoft for use on Windows systems. It's designed to host and serve web content, processing HTTP requests from clients, such as web browsers, and delivering web pages, files, and other resources in response to these requests.
It provides a platform for deploying and managing web applications, supporting various programming languages and technologies, and offering functionalities for security, scalability, and performance optimization in serving web-based content.
Functioning of IIS Web Servers
The IIS web server operates by first receiving requests from web browsers. Upon receiving a request, the server leverages its configuration settings to determine how to handle it, managing permissions, URL rewriting, and other server-specific configurations.
It then routes the request to the suitable module or handler, directing it to the appropriate destination based on the type of content requested—whether static, such as HTML pages or images, or dynamic content, processed by applications like ASP.NET or PHP.
For dynamic content, the associated scripting engine or application framework is activated to process the request, which might involve database interactions or executing specific code for content generation.
Following this, the server constructs an HTTP response, encompassing status codes, headers, and the generated content, whether HTML, JSON, or other data. This response is transmitted back to the client's web browser over the established connection.
The client then interprets and displays the received content. The server remains primed for further requests, managing multiple simultaneous inquiries efficiently.
Setting Up IIS on Windows
Setting up Internet Information Services on both Windows 10 and Windows Server involves enabling the feature and configuring options to create a web server environment.
Here's a simplified guide that focuses on enabling IIS and accessing its graphical user interface.
For Windows 10
Enable IIS Feature:
- Press the Windows key and type "turn windows features on or off."
- Select "Turn Windows features on or off."
- Check the box for "Internet Information Services" and expand the node.
- Within "Internet Information Services," expand "World Wide Web Services" and select additional features like "Application Development Features" if needed (such as ASP.NET, CGI, WebSocket Protocol).
- Click OK to enable the selected features. This may require a system restart.
Accessing IIS Manager:
- Once the installation is completed, open the IIS Manager by typing "IIS" in the Windows search or run "inetmgr" in the Run dialog (Win + R).
- This launches the IIS Manager graphical user interface where you can configure websites, application pools, and other settings.
For Windows Server
Enable IIS using PowerShell or Server Manager:
- Use PowerShell or Server Manager to install the "Web Role (IIS)".
Configure IIS Features:
- Enable desired IIS features and sub-features based on your requirements.
- Allow the installation process to complete.
Accessing IIS Manager:
- After installation, open the IIS Manager by typing "IIS" in the Windows search or running "inetmgr."
- This opens the IIS Manager GUI, allowing you to manage and configure your web server settings.
Always ensure that your server is secure, stays updated with the latest patches, and follows best practices for web server administration.
Key Features of IIS
Internet Information Services is a versatile and widely utilized web server known for its capacity to host ASP.NET websites and applications. However, its functionality extends beyond this, allowing it to serve as an FTP server, host WCF services, and support various other platforms, such as PHP, through extensions.
- Application Pools: Application pools are vital for managing IIS. They control and maintain various worker processes that handle the functioning of application instances, ensuring stability and performance.
- Authentication: IIS provides various authentication options, including Windows authentication, Basic authentication, and ASP.NET authentication. Windows authentication integrates well with Windows Active Directory, enabling users to log in to web applications using their domain accounts.
- Security: IIS is equipped with robust security capabilities, such as TLS certificate management, support for SFTP and HTTPS binding, and features to filter and control web traffic, enabling effective whitelisting and blacklisting. Administrators can set authorization and permission rules, log requests, and implement diverse FTP security features.
- Extensibility: IIS is highly adaptable. By extending its functionality, it can perform beyond hosting ASP.NET applications. This extensibility allows users to create a stable, flexible, and efficient server by integrating additional features and technologies.
- Support for Various Platforms: Beyond ASP.NET, IIS supports hosting services for a wide array of platforms, including PHP and others, through extensions and configurations.
These features make it a robust choice for IT administrators seeking a comprehensive and flexible web server solution.
