URL reservation is a crucial task for developers and system administrators who need to ensure that specific URLs are reserved for particular applications or services on a Windows system. This is especially important for applications that require specific ports or IP addresses to function correctly. In Windows, URL reservations can be managed using the netsh command-line tool. This article will guide you through the process of reserving URLs using netsh, ensuring that your applications run smoothly without conflicts.

Examples:

1. Reserving a URL:

To reserve a URL in Windows, you can use the netsh http add urlacl command. This command allows you to specify the URL, user permissions, and other parameters.

   netsh http add urlacl url=http://+:8080/MyApp user=DOMAIN\username

In this example:

• url=http://+:8080/MyApp specifies the URL and port to be reserved.


• user=DOMAIN\username specifies the user or group that is granted permission to use this URL.

2. Viewing Reserved URLs:

To view the list of currently reserved URLs, you can use the netsh http show urlacl command.

   netsh http show urlacl

This will display all the URLs that have been reserved on the system, along with the associated user permissions.

3. Deleting a URL Reservation:

If you need to remove a URL reservation, you can use the netsh http delete urlacl command.

   netsh http delete urlacl url=http://+:8080/MyApp

This command removes the reservation for the specified URL, freeing it up for other applications or services.

4. Reserving URLs for HTTPS:

You can also reserve URLs for HTTPS by specifying the https scheme in the URL.

   netsh http add urlacl url=https://+:443/MySecureApp user=DOMAIN\username

This reserves the URL for secure connections on port 443.

5. Granting Permissions to All Users:

If you want to grant permissions to all users, you can use the Everyone group.

   netsh http add urlacl url=http://+:8080/MyApp user=Everyone

This allows any user on the system to access the reserved URL.

By following these examples, you can effectively manage URL reservations in a Windows environment, ensuring that your applications and services have the necessary access to specific URLs without conflicts.
