FAQ
Why is my proxy not detected?
There's a chance this HTTP header test will not detect your proxy because certain proxies do not use HTTP headers. To find out more about your IP address and whether your proxy works or not, please visit our IP Address Lookup page.
What are HTTP response headers?
An HTTP response header is a part of a network packet sent by a web server to a browser as a response to an HTTP request. Web servers use it to deliver webpage content and other web-based data after a request is made through a web browser.
