@ -33,52 +33,58 @@ The following example will set up a reverse proxy listening on `127.0.0.1:13900`
|
||||
and will proxy these calls:
|
||||
|
||||
* `"/target/first"` will be proxied to `http://127.0.0.1:13901`
|
||||
|
||||
* `"/target/second"` will be proxied to `http://127.0.0.1:13902`
|
||||
|
||||
* All other URLs will be handled by `debug_request` function, that will display request information.
