ASP.NET and jQuery AJAX - strange problem

Question

Hi, I've got this strange problem...

I've got a web service running against jQuery front-end. When I run it through the integrated web server of VS2008 - it works great. But when I use the IIS itself - I get this error:

System.InvalidOperationException: Request format is invalid: application/json; charset=utf-8. at System.Web.Services.Protocols.HttpServerProtocol.ReadParameters() at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest()

the code for the AJAX:

$.ajax({ type: "POST", url: "http://localhost/MYSITE/WEBSERVICE.asmx/SOME_FUNCTION", data: '{ prm1: "' + p1+ '", prm2: "' + p2+ '", prm3: "' + p3+ '"}', contentType: "application/json; charset=utf-8", dataType: "json", .....

Any ideas why this happens?

The site is .NET 3.5 using "integrated managed pipeline pool".

Thanks, Roman
