Reverse Proxy

1. What's it?

Reverse Proxy would create a local WebServer that transparently proxies your traffic to a remote server. By doing this way, Proxyman can capture and log your traffic.

Reverse Proxy is useful when you are working on a client that doesn't support HTTP/HTTPS Proxy or the HTTP Proxy config is too complicated.

For instance, the majority of Command-Line apps would not respect the system HTTP/HTTPS proxies, so Proxyman could not capture its traffic. To resolve it, you have to either:

• Explicitly config an HTTP/HTTPS Proxy. It's complicated and depends on the network library you are using. Check out this troubleshooting to know further.

• Use Reverse Proxy.

Reverse Proxy is available on Proxyman 2.29.0+.

2. Benefit

• Reverse Proxy feature: You can connect to Proxyman local WebServer, and it will forward your traffic to the remote host. No need to set up an HTTP/HTTPS Proxy on your client.

• Import Reverse Proxy Setting from Charles Proxy.

• Preserve Host in Header.

• Automatically select the available port when creating a new entry.

• Able to use Breakpoint, Map Local, Scripting for Reverse Proxy traffic 💯.

3. How to use

1. Access Reverse Proxy tool from Tools Menu -> Reverse Proxy

2. Create a new entry by entering a Remote Host and Remote Port. For the Local port, Proxyman would select automatically. You can change to a different port, but it must be available.

3. Save.

4. On your client application, change the URL to http://localhost:<local_port> (e.g. http://localhost:10000)

5. Make a request and inspect the traffic from the Proxyman app.

Proxyman would perform SSL Handshake to your Remote Server if the port is 443. Otherwise, it considers as a normal HTTP WebServer.

Preserve Host in Header Fields allows you to preserve the original Host value. You should use it with caution because your remote server can reject the request due to a mismatched Host Value.
