Can I authenticate an iFrame page from the parent page? <p>I have a simple HTML page that rotates through several status pages that I display on several tv's around campus. I regularly update the page and the links. Many times the pages require authentication. It is a pain to remote to ever terminal to supply credentials. Some are HTTP authentication and some are some <code>&lt;form&gt;</code> based authentication baked into the site. Many times I can get around the <code>&lt;form&gt;</code> based authentication with HTML and JavaScript that post the right credentials.</p> <ol> <li><p>Is there a better way to get around the <code>&lt;form&gt;</code> based authentication from the host page? (below)</p></li> <li><p>Is there any way to get around the Server/HTTP based authentication from the host page without having to manually authenticate on ever display?</p></li> </ol> <p>By <code>&lt;form&gt;</code> authentication I mean that a <code>&lt;form&gt;</code> action generates a session cookie?<br> ( mikerobi, thanks for the comment)</p> <p>Here is the code for the host page </p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" &gt; &lt;head&gt; &lt;title&gt; Important Stuff &lt;/title&gt; &lt;script src="/scripts/jquery.js" type="text/javascript"&gt;&lt;/script&gt; &lt;style type="text/css"&gt; html, body, iframe { margin:0; height:100%; } iframe { display:block; width:100%; border:none; } &lt;/style&gt; &lt;script type="text/javascript"&gt; var link = new Array(); link[0] = "http://mycompany.intranet/"; link[1] = "http://mycompany.intranet/weather.htm"; link[2] = "http://mycompany.intranet/systemstatus/"; var linkIndex = 0; setInterval("doSomething()", 10000); function doSomething() { if (linkIndex &gt;= link.length) { // reload in case the page has been updated window.location.reload(); } $("#frame").attr("src", link[linkIndex]); linkIndex++; } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;iframe id="frame" src="http://mycompany.intranet/"&gt;&lt;/iframe&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>
