    copied!<p>I am trying to get Uploadify to work with my site but I am getting a generic "HTTP Error" even before the file is sent to the server (I say this because Fiddler does not show any post request to my controller.</p> <p>I can browse correctly for the file to upload. The queue is correctly populated with the file to upload but when I hit on the submit button the element in the queue get a red color and say HTTP Error.</p> <p>Anyway this is my partial code:</p> <pre><code>&lt;% using ( Html.BeginForm( "Upload", "Document", FormMethod.Post, new { enctype = "multipart/form-data" } ) ) { %&gt; &lt;link type="text/css" rel="Stylesheet" media="screen" href="/_assets/css/uploadify/uploadify.css" /&gt; &lt;script type="text/javascript" src="/_assets/js/uploadify/swfobject.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="/_assets/js/uploadify/jquery.uploadify.v2.1.0.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $(document).ready(function() { $("[ID$=uploadTabs]").tabs(); var auth = "&lt;% = Request.Cookies[FormsAuthentication.FormsCookieName]==null ? string.Empty : Request.Cookies[FormsAuthentication.FormsCookieName].Value %&gt;"; $('#fileInput').uploadify({ uploader: '/_assets/swf/uploadify.swf', script: '/Document/Upload', folder: '/_uploads', cancelImg: '/_assets/images/cancel.png', auto: false, multi: false, scriptData: { token: auth }, fileDesc: 'Any document type', fileExt: '*.doc;*.docx;*.xls;*.xlsx;*.pdf', sizeLimit: 5000000, scriptAccess: 'always', //testing locally. comment before deploy buttonText: 'Browse...' }); $("#btnSave").button().click(function(event) { event.preventDefault(); $('#fileInput').uploadifyUpload(); }); }); &lt;/script&gt; &lt;div id="uploadTabs"&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="#u-tabs-1"&gt;Upload file&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;div id="u-tabs-1"&gt; &lt;div&gt; &lt;input id="fileInput" name="fileInput" type="file" /&gt; &lt;/div&gt; &lt;div style="text-align:right;padding:20px 0px 0px 0px;"&gt; &lt;input type="submit" id="btnSave" value="Upload file" /&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;% } %&gt; </code></pre> <p>Thanks very much for helping!</p> <p><strong>UPDATE</strong>:</p> <p>I have added a "onError" handler to the uploadify script to explore which error was happening as in the following sample</p> <pre><code>onError: function(event, queueID, fileObj, errorObj) { alert("Error!!! Type: [" + errorObj.type + "] Info [" + errorObj.info + "]"); } </code></pre> <p>and discovered that the info property contains <strong>302</strong>. I have also added the <strong>"method"</strong> parameter to uploadify with the value of <strong>'post'</strong>.</p> <p>I am including my controller action code for information. I have read many posts regarding uloadify and it seems that I can use an action with the following signature...</p> <pre><code>[HttpPost] public ActionResult Upload(string token, HttpPostedFileBase fileData) { FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(token); if (ticket!=null) { var identity = new FormsIdentity(ticket); if(identity.IsAuthenticated) { try { //Save file and other code removed return Content( "File uploaded successfully!" ); } catch ( Exception ex ) { return Content( "Error uploading file: " + ex.Message ); } } } throw new InvalidOperationException("The user is not authenticated."); } </code></pre> <p>Can anybody provide some help please?</p>
