Problem with AJAX in C# application on IIS

Question

I am facing issues with AJAX in my C# application running on IIS. The application works fine on the local environment and test environment, but AJAX functionality fails on the server. I have checked the Request Filter and unlocked some .cs and .csproj files, but there are no server logs generated. Can someone help me troubleshoot this issue?

Here are a few troubleshooting steps to resolve the AJAX issue in your C# application on IIS:

1. Check the AJAX Request URL: ensure that the AJAX URL is correct in the production environment. Sometimes relative URLs behave differently on different environments. If you're using relative paths, try switching to absolute paths.
2. Check Server Permissions: verify that the IIS server and application pool have sufficient permissions to access the required resources. This includes file system permissions, database access, or external API access.
3. AJAX Timeouts: If requests are timing out in production but working in test/local, there may be a server performance issue or a configuration limiting request execution time.
