No, there shouldn't be anything in the way. It's a simple page that shows company logo and a few links to reports on the left side, and iframe on the right side. When a link on the left is clicked, the iframe loads the report. I was using this sample.
<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server"><script type="text/javascript"> // Update embed report function updateEmbedReport() { // Check if the embed url was selected var embedUrl = document.getElementById('<%=tb_EmbedURL.ClientID%>').value; // To load a report do the following: // 1: Set the url // 2: Add a onload handler to submit the auth token var iframe = document.getElementById('iFrameEmbedReport'); iframe.src=embedUrl; iframe.onload = postActionLoadReport; } // Post the auth token to the iFrame. function postActionLoadReport() { // Get the app token. accessToken = document.getElementById('<%=hidReportAppToken.ClientID%>').value; // Construct the push message structure var m = { action: "loadReport", accessToken: accessToken }; message = JSON.stringify(m); // Push the message. iframe = document.getElementById('iFrameEmbedReport'); iframe.contentWindow.postMessage(message, "*"); }</script><div style="overflow:hidden; height:100%"><table width="100%" height="100%" cellspacing="0" cellpadding="0"><tr><td width="300" height="100%" style="background-color:#124C8F" valign="top"><br /><div align="center"><img src="images/NMBS-logo.png" width="200" /></div><br /><br /><br /><br /><aspanel ID="PanelReports" runat="server" Visible="true"><table width="100%" cellpadding="4" border="0"><tr><td valign="top"><asp
