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.

When configuring dynamic compression in IIS, selecting content types reasonably can improve performance. First enable the dynamic compression module, install and configure web.config or IIS manager through the server manager. Secondly, set appropriate content types, such as HTML, CSS, JavaScript, and JSON, text content is suitable for compression, while pictures and videos are not suitable. Finally, pay attention to the impact of client compatibility and performance, monitor CPU load, client support status and small file compression effects, and adjust the configuration based on actual traffic to obtain the best benefits.

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

To solve the IIS application pool authentication account permission problem, first, you need to confirm the identity account used by the application pool. The default is IISAppPool{AppPoolName}, which can be viewed or modified through the IIS manager; secondly, make sure that the account has corresponding permissions to the website physical path (such as D:\MyWebSite). The operation steps are: Right-click the folder → Properties → Security → Edit → Add the corresponding account and set the read, write and other permissions; common errors such as 401.3 is due to lack of read permission, 500.19 may be due to insufficient permissions for web.config file, and failure to upload may be due to lack of write permissions; pay attention to whether the inheritance permissions are effective, the UNC path needs to be configured with a username and password, and it may be necessary to modify it after the username and password.
