Hi,

is this working in Mozilla too?

for me the Microsoft.XmlHttp is very strange?

Isn't there a more 'standard' way?:)

Good point, Tamas!

The focus of the post is about server side - how WCF exposes itself to AJAX clients, but your comment is valid and very relevant.

Any client that can issue such HTTP request can consume WCF services that exposes itself via webHttpBinding. I am not in the know how it is done with Mozila in "standard way", but in IE Microsoft.XmlHttp is the way to do. Search the web and you will find plenty code samples I am sure. Once you found the sample construct the following HTTP request using your code. I captured it using Fiddler. Make sure you substitute few details relevant to your environment.

Very interesting - but I wish you had written this post last week when I was trying to figure this out!! What is the best way to secure these services (reasonably secure but not requiring a whole lot more Javascript code) so that unauthenticated requests are not accepted?

Nick!

Great to hear you found it interesting. I am going to address security and other details, like JASON vs XML encoding, in my next posts.

Basically speaking - there should be nothing special about authenticaion. In case of windows integrated or other type of authentication XmlHttp was used for long ago before WCF and it "knows" how to pick up on right athentication scheme already in use. No extra JavaScript is requred. Do you struggle with any particula issue that you want to share? Would love to hear about it.

Thanks
