HTTP proxy fiddler (iii)

HTTP proxy artifact fiddler

Fiddler is a powerful Web debugging tool that can record HTTP requests from all clients and servers. Fiddler startup, the default IE proxy is set to 127.0.0.1:8888, while other browsers need to be set manually.

Working principle

Fiddler is working as a proxy Web server, which uses proxy addresses: 127.0.0.1, Port: 8888

Fiddler crawling HTTPS settings

1. Start Fiddler, open the Tools > Telerik Fiddler Options in the menu bar and open the Fiddler Options dialog box.

To set the Fiddler:

• Open the toolbar->tools->fiddler Options->https,
• Select Capture HTTPS connects (capture HTTPS connection),
• Check decrypt HTTPS traffic (decrypt HTTPS communication)
• In addition, we want to use Fiddler to get HTTPS requests for all the processes in the machine, so the drop-down menu in the middle selects ... from all processes (all processes)

• Check the Ignore server certificate errors below (ignoring server certificate errors)

3. Configure Windows Trust this root certificate for Fiddler to resolve the security Warning: Trust root Certificate (Trusted root certificate).

4.Fiddler main Menu Tools, Fiddler options...-> Connections

• Select Allow remote computers to connect (allows connection remotely)

• Act as System Proxy on startup (as a system boot agent)

5. Restart the fiddler for the configuration to take effect (this step is important and must be done).
