Q:

renewing facebook oauth token BEFORE expiration

Is it possible to renew the long-term oauth token for facebook before it expires, and if so, how is that accomplished? So far it seems facebook will only give back the old token with the same expiration date.
Edit: using server-side authentication, and not finding in the docs specific info on how to request a new short lived token and exchange it for a long-term token using server-side workflow.

A:

how is that accomplished?

By getting a new short-lived user access token first, and then sending it to the endpoint for extension.
