Registering Remote Access Callback URL

Hi,

I have an application that integrates with Salesforce using the REST API. Currently, it is registering the Callback URL in the Deploy - Remote Access setup, Callback URL to the following.

https://localhost:3000/identities/salesforce/callback

Everything seems to work, as my web application gets the callback. However, I want to deploy the application on multiple servers, and each has its own web server. Is there a way to "register" multiple callbacks? I tried the following and it did not work.

https://localhost:3000/identities/salesforce/callback,https://mydomain-name.net/identities/salesforce/callback

There is a web application listening on https://mydomain-name.net. How do I do this?

Thanks.
