Web Request Viewer

Send a request to this server and it tells what your request look like.

Use cases

It's hard to know the exact information of a request sent out from your code. The best and eaiset way is of course have a real server listening to your requests and reply with what information they can see from your request.

For example, if you are writing a web scrapying bot and you want to change your user-agent to hide this bot, how can you make sure the request sent indeed hides your user-agent?

Or if request headers contains any information that could leak your identity.

What about you are using a VPN and you are unsure whether the VPN indeed hides your IP. You can send to request to this server and check the IP this server sees.


Some VPN protocols like shadowsocks work in layer 4 (transport layer) in the 7-layer OSI model, some work in layer 3 (network layer). It feels the same in browsers.

If you use terminal (curl command or git), VPNs like OpenVPN automatically handles the traffic for you. While VPNs using shadowsocks requires extra http/socks proxy configuration.

If you are a hacker/pentester, how can you verify whether you hide your identity behind VPN successfully? Simply send a request to the request viewer server and compare with your real ip. It also returns the intermmediate routers' ip.
