ASP.NET MVC: How does one add authentication to RSS Feeds?

I have seen a few examples of how to create RSS feeds using ASP.NET MVC, either by creating an Action or through an HttpHandler.

I need to authenticate feeds and am wondering how this is to be done (and supported by RSS readers rather than just browsing to the page/xml through a browser) and how would authentications differ between an MVC Action or HttpHandler?

I would expect most readers to support typical (basic and digest) authentication. E.g. twitter's feeds require authentication.

There are multiple ways to do it.

The best approach, according to me, is using REST architecture with credentials in either the path or as post-data (1st approach preferred).

1st Approach:

Step1: GET http://www.myserver.com/myfeed.rss/username/query => this should return a random value Step2: GET http://www.myserver.com/myfeed.ress/username/hashed-password => The hashed password expected from the client is hash(<random-value>+<password>).

This will serve two purposes:

  1. Original password is never transmitted on the wire
  2. Random value ensures that the hash is unique, and hence, cannot be reused.

You may want to set an expiry date/time for the username + random-value combination with other IP related security actions to ensure that session hijack cannot happen.

EDIT:

Use HTTP Handler for the path="myfeed.rss" with verbs="GET" in web.config

the simplest way is to give each client an unique url. so in this case you always will know who is querying the feed.

http://site.com/rss/<some_secret_hash_here>

in other hand - you can use urls with standart user:password pair like:

http://user:[email protected]/rss/blabla.xml

and just parse user:password.

i prefer to use first one.
