Calling WCF service from multiple domain clients

Question

I have a WCF service that I access fram Javascript using AJAX and JSON. The client and the service is on the same site (domanin). It works great.

I now need to call the same service from several other sites/domains. How is this done? So far I have not found any resources describing this scenario.

These sites uses ASP.NET 4.0 (C#).

I agree that you need JSONP but I don't agree with using custom behavior from WCF 3.5 samples. WCF 4 has a native support for JSONP by turning on crossDomainScriptAccessEnabled in the webHttpBinding configuration. I wrote an example in this question.

Thanks, Ladislav. The `crossDomainScriptAccessEnabled` led me to this great article, http://bendewey.wordpress.com/2009/11/24/using-jsonp-with-wcf-and-jquery/. – Jon Apr 22 '11 at 17:53
