HTTP Status Code 450 – Blocked by Windows Parental Controls

The HTTP status code 450 is a Microsoft-specific extension to the HTTP protocol. This status code indicates that the requested resource is blocked due to restrictions imposed by Windows Parental Controls. This mechanism is designed to help parents manage and restrict access to certain websites or online content for users on a Windows operating system.

Example 1: Access Denied by Parental Controls

HTTP/1.1 450 Blocked by Windows Parental Controls
Content-Type: text/html; charset=UTF-8
Content-Length: 0
        

In this example, a user attempts to access a website that has been blocked by Windows Parental Controls. The server responds with a 450 status code, indicating that the content is not accessible due to the restrictions set by the parental controls.

Example 2: Blocking Adult Content

HTTP/1.1 450 Blocked by Windows Parental Controls
Content-Type: text/html; charset=UTF-8
Content-Length: 0
        

Here, a user tries to visit a website categorized as adult content. The Windows Parental Controls, configured to block adult content, intercept the request and return a 450 status code, thereby preventing access to the site.

### Explanation:

– **Description**: The 450 status code is specific to Microsoft and is used in situations where Windows Parental Controls are in place. When a user tries to access a blocked site, the server responds with this code to signal that the content is restricted.

– **Examples**:
– **Example 1** shows a generic response where a user is denied access due to parental controls. The response indicates that no content will be displayed as access is restricted.
– **Example 2** illustrates a scenario involving adult content where the same 450 status code is returned, preventing access and ensuring compliance with the parental control settings.

– **Summary**: This status code is useful for parents to ensure safe browsing experiences for their children by blocking access to inappropriate content. It is important to note that 450 is not an official HTTP status code but rather an extension used within Microsoft’s ecosystem.
