Localhost Traffic
Localhost traffic may not go through the Reqable proxy server even when the system proxy is configured correctly, so additional setup is required. The steps differ by operating system:
Windows
To listen to localhost traffic, you need to enable the Loopback option in Reqable. Note that this option is enabled by default.
Mac & Linux
Use the Mirror feature to map localhost. For example, map localhost to go as follows:

After the configuration is complete and the mirror switch is turned on, go will be used as the alias of localhost, and then localhost in the URL can be replaced by go.
Old link: http://localhost:3000/
New link: http://go:3000/
You can use other aliases instead of go; this is only an example.
For the example above, you can include the port when configuring the mirror—use go:3000. Then http://go is equivalent to http://localhost:3000, so you do not need to specify the port in every URL.
