I am new to Brightspace and been fiddling with the remote plugins sample (logo). I can load the sample logo project, but cannot get it to insert into the page. I have uploaded the file but get a 404 error on submit. Can someone `

```js
   $( document ).ready(function() {
            $('#submitFormButton').click( function() {
                 $.ajax({
                    url: "/getisfdetails",
                    data: {
                        image: $("input[name='image']:checked").val()
                    },
                    success: function(response){
                        $("input[name='lti_message_type']").val(response.lti_message_type);
                        $("input[name='lti_version']").val(response.lti_version);
                        $("input[name='content_items']").val(response.content_items);
                        $("input[name='oauth_version']").val(response.oauth_version);
                        $("input[name='oauth_nonce']").val(response.oauth_nonce);
                        $("input[name='oauth_timestamp']").val(response.oauth_timestamp);
                        $("input[name='oauth_consumer_key']").val(response.oauth_consumer_key);
                        $("input[name='oauth_callback']").val(response.oauth_callback);
                        $("input[name='oauth_signature_method']").val(response.oauth_signature_method);
                        $("input[name='oauth_signature']").val(response.oauth_signature);
                        $("#isfForm").prop('action', response.lti_return_url);
                        $("#isfForm").submit();
                    }
                });
            });

    });

` how do you set this cookie in the javascript? I believe a cookie needs to be set??? and I do not see how to set it? or maybe I am missing something else that is not noted in the documentation.
