Also tried
STEP 1. in my WCF service code (it's in C# for those who cares)
WebOperationContext.Current.OutgoingResponse.ContentType = "text/
javascript";
STEP 2.
var myAjax = new Ajax.Request(
url,
{
method: 'get',
contentType: 'text/javascript',
parameters: oParam,
evalJSON: 'force',
onComplete: showResponse,
onFailure: function() {
alert("FindBlog call failed.");
}
}
);
No luck... not sure if IIS on my XP box has anything to do with it...
