    <p>On one of our intranet pages, I'm using <code>cffileupload</code> to upload multiple photos:</p> <pre><code>&lt;cffileupload extensionfilter=".jpg,.jpeg,.png,.gif" url="/submissions/photo_gallery.cfm" onerror="errorissue" width="600" addbuttonlabel="Browse..." maxuploadsize="100"&gt; </code></pre> <p>The url for this tag points back to the same page where I process the images:</p> <pre><code>&lt;!--- Define the upload path ---&gt; &lt;cfset upload_path = "C:\websites\images\photo_gallery\"&gt; &lt;!--- Upload all the files ---&gt; &lt;cffile action="upload" destination="#upload_path#" nameconflict="makeunique" result="uploaded_file"&gt; </code></pre> <p>In IE and Chrome, this works. In Firefox, I get a 401 error. It appears to be related to how the browsers authenticate. IE and Chrome use Windows authentication while Firefox prompts when entering the site for username/password. Nothing shows up in the Coldfusion logs, but the IIS logs show this (with the IP x'd out):</p> <blockquote> <p>2013-05-09 19:16:07 xxx.xxx.xxx.xxx POST /submissions/photo_gallery.cfm CFID=5546&amp;CFTOKEN=75080018 80 - 172.28.30.99 Shockwave+Flash 401 2 5 0</p> </blockquote> <p>The previous line in the log is from loading the page. As you can see, my username is showing up in this line (edited for security):</p> <blockquote> <p>2013-05-09 19:16:07 xxx.xxx.xxx.xxx GET /includes/js/shared.js - 80 DOMAIN\username xxx.xxx.xxx.xxx Mozilla/5.0+(Windows+NT+6.1;+WOW64;+rv:20.0)+Gecko/20100101+Firefox/20.0 304 0 0 218</p> </blockquote> <p>So, cffileupload seems to be losing my username. However, the session.urltoken in the cffileupload url is the same as it is in on the page with the multiple file uploader (the calling page). So, you'd think the authentication would stick.</p> <p>Also, I can get it to work in Firefox when I go into IIS7 and enable Anonymous Authentication on the Jakarta virtual directory (and disable Windows Authentication on the same). But, this is not a usable solution.</p> <p>Can anyone suggest another solution?</p>

    1. COIs the browser prompting for the user's credentials? How is Firefox "not working", is it returning a 401 or 403 status code? What version of Firefox (and the other browsers)?

    2. COYes, I'm sorry. I should have mentioned that. It's prompting for credentials to get to the site. cffileupload is returning a 401 error. In the IIS logs, it shows the following: 2013-05-09 19:16:07 xxx.xxx.xxx.xxx POST /submissions/photo_gallery.cfm 80 - xxx.xxx.xxx.xxx Mozilla/5.0+(Windows+NT+6.1;+WOW64;+rv:20.0)+Gecko/20100101+Firefox/20.0 401 2 5 15 (I x'ed out the IP)

    3. COYou should see a 401 for the initial request, that should force the browser to authenticate and prompt for the user's credentials. What do the logs show on subsequent requests (after passing the credentials)? Also, are you including the domain name when supplying credentials "domainname\username"? That is sometimes required for non-IE browsers with Windows Domains.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
