Using CORS (Cross-Origin Resource Sharing) to restrict other domains from accessing your website can be very necessary depending on the specific context. Here are some reasons why you might want to use CORS:
- Security: If you don’t want your data to be accessed by other domains without permission, CORS helps you control this. Only allowed domains can send requests to your server and receive responses.
- Preventing API Abuse: If you have a public API and don’t want it to be misused by other websites, using CORS to allow access only from specific domains is essential.
- Resource Control: CORS helps protect your resources from being used without permission by unwanted websites. This is especially important if you provide resources like images, videos, or data.
- Avoiding Cross-Site Scripting (XSS) Vulnerabilities: CORS can help reduce the risk of XSS by controlling requests from untrusted sources.
However, if your website only provides public content and you don’t mind other domains accessing it, then CORS might not be necessary. CORS is mainly used in situations where there is a need to protect data or control access to resources.
