I've also been having this problem. I'm sending a comment to the server, and returning a JSON object to write the comment to the page w/ o a refresh.
Request.JSON = new Class({ ... initialize: function(options){ this.parent(options); this.headers.extend({'Accept': 'application/json', 'X-Request': 'JSON'}); }, success: function(text){ this.response.json = JSON.decode(text, this.options.secure); this.onSuccess(this.response.json, text); } }); This is the JSON request method, have you tried: this.headers.extend({'Accept': 'application/json', 'X-Request': 'JSON'}); ??
