# X-XSS Protection

The **X-XSS Protection** feature for Dynamic Content Acceleration operates the same way as in Static Content Delivery.\
It adds the `X-XSS-Protection` header to viewer responses to enable built-in browser filtering mechanisms on browsers that still support the header. This option is primarily intended for legacy environments and does not alter origin requests, caching behavior, or modern browser security posture.

For configuration details, header behavior, and examples, refer to the main documentation:\
