For fixing cache issue in configuration file, we need to replace the full url to path without host:port/api/v1.
Ex :
url: http://localhost:8080/api/v1/http/any?url=test.com
will be :
path: /http/any?url=test.com

For doing this, we need to add apiPath notion in front end.
By default apiPath = front hostname:port + /api/v1 but it's overridable in url params

After this, we can change the actual monitoror path :
http://localhost:8000/?config=http://localhost:8080/api/v1/config?path=./test/faker-config.json
by this :
http://localhost:8000/?apiPath=http://localhost:8080/api/v1&configPath=./test/faker-config.json
Or (in production)
http://localhost:8080/?configUrl=http://github.com/...
