It depends on what you need to do. I would not use DCOM over the Internet - it's just not a scalable option for anonymous users.
For distributed apps I would build a front end that communicates with a
Web server that passes through COM objects on the server.
There are a couple of articles on my Web sites that demonstrate both aspects
(accessing content over HTTP and running remote components in this case
using XML messaging).

The XML messaging article in particular addresses your particular question
although your implementation may vary.
