Free Proxy Headers Test

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.

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. Keep in mind that a transparent proxy usually does not modify the HTTP header and is visible to a transparent proxy detector.

Residential proxies are the best proxies to hide your IP address due to the high level of anonymity. They successfully pass the proxy test by modifying the X-Forwarded-For HTTP header to show the proxy IP address, instead of the original client.

A proxy test may not detect your proxy if it successfully obfuscates your IP address and modifies the HTTP header to remove proxy-identifying information from it. You can use IPRoyal's Proxy Tester tool to target a specific URL and verify whether your proxy works with it.

An HTTP proxy is a proxy server that intercepts clients' traffic and routes it to web servers using HTTP protocol. Forward proxies usually require client input and customization, while a transparent proxy server is invisible to the client, like reverse proxies that redistribute traffic across web servers.
