title: Interceptors in Angular2
body: <p>I am trying to build a demo app on <strong>Angular2.beta.0</strong> which would have login mechanism and then all the other API calls would have the acquired session token sent via the headers.</p>
  
  <p>In angular 1x, I could write an Interceptor which would add the token to the http header in a separate code, I would like to know if angular2 has such kind of mechanism or any other recommended way to do this.</p>
