Hey.

If I chain two HttpPromise with

return $http.get('/foo').then($http.post('/foo'))

the return value is a Promise and not a HttpPromise.
If chained HttpPromises would still be HttpPromise their usage would be more consistent

Advantages:

• Simple: On Success the next HttpPromise could be called directly with the body and not with {data, status, header, config}
• Abstraction: Have all the power of Promises without missing out the features of HttpPromises
• Consistency: Interacting with chained Requests would be in the same way as with a normal request
