I needed to add a customer http header to the outgoing request of a web service call (for authentication purposes). With old web services it was easy to do this, but with WCF it’s a bit tricker. The good thing is that WCF is *very* extensible.

I ran into a bit of a issue today at a client with Windows Authentication and WCF services (it seems like a very common problem) where I was using a host header in IIS to test a web application I was working on.

Here’s a demo. You can click on the headers to sort or type into the textbox to filter by FirstName or LastName.
