OAuth authentication: prepend server to relative server urls

[ilveroluca]

Hi,

I'm configuring Restish as an OAuth2 client for an API (https://api.dev.lifemonitor.eu). I noticed that if I configure

? Auth parameter authorize_url oauth2/authorize
? Auth parameter token_url oauth2/token

Restish ends up pointing my browser at oauth2/authorize?client_id=..., rather than https://api.dev.lifemonitor.eu/oauth2/authorize?client_id=...
