HTTP Headers Checker
See every HTTP header your browser sends and check your proxy anonymity level in real time.
Analyzing your headers...
Inspecting all request headers for proxy fingerprints
Elite Proxy
No proxy-related headers are sent. Websites cannot distinguish your connection from a direct one. This is the highest level of anonymity, typical of mobile 4G proxies and premium residential proxies.
Anonymous Proxy
Your real IP address is hidden, but headers like Via or Proxy-Connection reveal that a proxy is being used. Websites know you are behind a proxy but cannot see your original IP address.
Transparent Proxy
Your original IP is exposed via X-Forwarded-For header, and the proxy is fully detectable. This offers zero anonymity and is commonly seen with corporate or ISP-level proxies.
Why Headers Matter
Anti-bot systems inspect HTTP headers to detect proxies and VPNs. Even one proxy-revealing header can get you blocked. Mobile 4G proxies from Proxy Poland pass zero proxy headers, ensuring elite-level anonymity for all your tasks.
Understanding HTTP Headers & Proxy Anonymity
What HTTP headers reveal about you
Every time your browser makes a request, it sends dozens of HTTP headers containing information about your device, browser, language preferences, and connection. Headers like User-Agent, Accept-Language, and Referer are standard. However, when you use a proxy, additional headers like X-Forwarded-For, Via, and Proxy-Connection may be injected, revealing that your traffic is being routed through an intermediary. This tool shows you exactly what your server sees.
Proxy anonymity levels explained
Proxies fall into three anonymity categories. Transparent proxies pass your real IP in X-Forwarded-For — websites see both the proxy and your original IP. Anonymous proxies hide your IP but still add headers like Via that reveal proxy usage. Elite (high-anonymity) proxies send zero proxy-related headers, making your connection indistinguishable from a direct one. Only elite proxies provide true anonymity.
Headers that expose proxy usage
Key headers to watch: X-Forwarded-For (contains original IP chain), Via (proxy software identification), Proxy-Connection (non-standard proxy header), Forwarded (standardized proxy header), X-Real-IP (reverse proxy header), and X-Originating-IP. If any of these appear in your request, websites and anti-bot systems can detect you are using a proxy and may block or fingerprint your connection.
Why mobile proxies are elite-level
Mobile 4G proxies from Proxy Poland use real Orange LTE SIM cards in physical modems. Because traffic exits through a genuine mobile carrier network — not a datacenter — no proxy headers are injected. The connection looks identical to a regular smartphone user. This makes mobile proxies inherently elite-level, passing even the most sophisticated header inspection and browser fingerprinting checks used by Google, Facebook, and other major platforms.
