Configuring Tracing and Debugging Using Failed Request Tracing in IIS
FailedRequestTracing is a debugging tool provided by IIS to troubleshoot problems such as 500 errors or slow page loading. 1. First install the module through "Add Roles and Functions"; 2. Enable the tracking function in IIS Manager; 3. Configure tracking rules, such as triggering by status code or execution time; 4. Logs are stored in inetpub\logs\FailedReqLogFiles by default; 5. Use FailedRequestTracingViewer to view XML logs and analyze the problems of each stage of the request; 6. It is recommended to enable, close and clean the logs regularly as needed, and combine other logs to improve the inspection efficiency.

Optimizing IIS Application Pool Performance Settings
Optimizing the performance of IIS application pool requires balancing resources and stability. Key points include: 1. Setting the appropriate recycling time, it is recommended to recover at low peaks every day or trigger it according to memory; 2. Control the memory upper limit (such as 512MB~1GB) to prevent resource scrambling; 3. Enable fast fault isolation, adjust the error threshold to avoid misblocking; 4. Adjust the idle timeout time, and improve the response speed with preloading.

Setting Up Permanent or Temporary URL Redirects Using the IIS HTTP Redirect Module
To enable and configure IIS's HTTPRedirect module to implement 301 or 302 redirect, you need to complete the following steps in turn: First, enable the HTTPRedirect module in the Windows function; then select the site or page in the IIS manager, double-click "HTTPRedirect" to set the target URL and select the redirect type (permanent or temporary); finally pay attention to avoid conflicts with other modules, clear browser cache, ensure correct permissions, and achieve more granular control through the web.config file.

Migrating Websites from Older Versions of IIS to IIS 10
The following steps should be paid attention to when migrating a website to IIS10: 1. Confirm that the target server is Windows Server 2016 and above and install the corresponding .NETFramework version; 2. Enable IIS roles and required subcomponents such as CGI, ISAPI extensions, etc.; 3. Use WebDeploy tools to export the old site and import the new server, or manually copy the file to configure binding and permissions; 4. Check whether the .NETCLR version of the application pool matches the pipeline pattern; 5. Test website access, verify custom error pages, URL rewriting rules, MIME types and HTTP response headers; 6. Configure NTFS permissions, and recommend using "application pool identifier" and combining the principle of minimum permissions; 7.

Configuring Authentication Methods (Windows, Forms, Basic) in IIS
Windows authentication is suitable for internal applications and is automatically authenticated through domain accounts; the steps are to open IIS Manager, select a site, enable Windows authentication, and ensure HTTPS is used. Forms authentication is suitable for custom login pages. You need to configure the login URL and timeout time in web.config, and develop a login page to verify users, encrypt your password and use HTTPS. Basic authentication is lightweight but not secure. It is only used when HTTPS is enabled. It needs to be enabled in IIS and cooperate with local or domain accounts. Password leakage is often caused by ignoring HTTPS.

Managing MIME Types for Specific File Extensions in IIS
MIME type is a mechanism by which the server identifies file content types, and missing or incorrect configuration can cause resource loading to fail. There are two main ways to manage MIME types with specific extensions in IIS: 1. Add or modify them through the IIS manager graphical interface; 2. Configure in the web.config file. Common MIME types that need to be added manually include .webmanifest, .woff2, .svg, .mp4 and .pdf. Notes include inheritance issues, IIS version differences and browser cache impact. Proper configuration is essential to ensure that modern web resources are loading properly.

Configuring Request Limits and Connection Timeouts in IIS
To limit the size of client requests, the maxAllowedContentLength parameter can be modified in web.config, such as setting it to 104857600 (100MB), and synchronizing the maxRequestLength of ASP.NET at the same time; to reasonably set the connection timeout time, it can be modified through the IIS manager or appcmd.exe command, with the default of 120 seconds, and the API scenario is recommended to set it to 30-90 seconds; if the request queue is full, you can increase MaxClientConn and QueueLength, optimize application performance, and enable load balancing to relieve stress.

Deploying ASP.NET Core Applications to an IIS Environment
When deploying ASP.NETCore applications to IIS, you need to pay attention to the following key points: 1. Install the .NETCore runtime and HostingBundle, otherwise it will cause HTTP500 errors; 2. Make sure to include web.config when publishing the application and select the appropriate publishing mode; 3. Configure the IIS site and application pool, set "unmanaged code" and correct permissions; 4. Check the logs and manually test the Kestrel startup situation when there is a problem.

Configuring HTTP Response Headers for Caching and Security in IIS
Configuring HTTP response headers in IIS to optimize cache and improve security can be achieved by setting cache-related headers and adding security response headers. 1. Set cache-related headers: By configuring the clientCache element in the web.config file, set the Cache-Control and Expires headers for static resources, for example, use cacheControlMaxAge to specify the cache time, and fine-grained control can also be performed for specific file types (such as .jpg), but avoid HTML page caching for too long. 2. Add security-related headers: Configure X-Content-Type-Optio through customHeaders in web.config
