Debug message "Resource interpreted as other but transferred with MIME type application/javascript'


OK, I understand what the messages means , but I'm really not sure what's causing it. I'm using Safari and the Web Inspector on Mac OS X, by the way.



I've got the following in my document head:




<script src="http://local.url/a/js/jquery.js" type="text/javascript"></script>
<script src="http://local.url/a/js/jquery.inplace.js" type="text/javascript"></script>



jquery.js is handled fine, but the other file causes the warning. It also seems that the javascript in this file never gets executed.



The file is being served via mod_deflate , so it is gzip encoded, but so is the other file.



Has anybody got any ideas what's causing this, or how to resolve it?



Cheers all, Gaz.

  1. seems to be a bug in safari / webkit. maybe this one, or any of these. try upgrading your safari. if there is no more recent stable version, try the 4 beta.

  2. An image with an empty "src" attribute generates this error under Windows-Chrome:

    <img src="">


    ... whereas ...

    <img>


    ... does not.

    I arrived here because my ajax resultset was returning "src" data which was empty yet the img was still being inserted into the page.

  3. I don't thing is a bug,
    try adding the mime type to your .htaccess file
    for example put or add the following content to your .htaccess file (which should be in the same place of your .js or above folders)

    #JavaScript
    AddType application/x-javascript .js


    This solved my tree "Resource interpreted as other but transfered ... " Warnings.
    Everytime you have that kind of warning it means you don't have enough info in your .htaccess file.

    BTW1: Since you are modifying .htaccess file, make sure you restart your server.

    BTW2: I also could clear same warnings for GIF files in Safari 4 with this:

    #GIF
    AddType image/gif .gif


    BTW3: For other file types: see w3schools list or htaccess-guide

  4. This warning appears because no default script type is specified. Try adding the following directive to your HTML file:

    <meta http-equiv="content-script-type" content="text/javascript">

    You can read more about default scripting specifications here:

  5. Solved!

    I have had this error for several days. It was driving me crazy because it didnt allow me to use firefox firebug's script debugger. Finally, my error was solved when I removed an empty url in a "background-image: url()" style property.

    This has been so much a pain than I really hope somebody can use this advice.

  6. You need to use a tool to view the HTTP headers sent with the file, something like LiveHTTPHeaders or HTTPFox are what I use. If the files are sent from the webserver without a MIME type, or with a default MIME type like text/plain, that might be what this error is about.

  7. It is because of the period in the file name. It is stupid, but anytime there is a period in the js file name you will get this error, and I have come across situations where it will actually prevent the js file from loading.

  8. It seems like a bug in Safari's cache handling policies.

    Workaround in apache:

    Header unset ETag
    Header unset Last-Modified

  9. I just got this and solved it locally on my mac. For some reason the javascript file in question had bad permissions. I noticed when I looked at it in firebug I was getting a 403. I hope that helps anyone.

  10. I had the same issue with a css file instead of javascript. (using the xitami webserver)

    what fixed for me was adding under the MIME section of xitami.cfg:

    css=text/css

  11. I found out that the naming of my css files was in conflict with the proxy filters

    www.dating.com (which is not my site) was blocked and my css and js files were called dating.css and dating.js. The filter was blocking this. Maybe that is the case with some of you, working on corporates systems.

  12. This bug seem to have resurfaced (Noticed it November 2010)

    I think the WebKit bug reports involved are this one and this. Essentially it boils down to incorrect cache handling when doing an If-Modified-Since which get a 304 response.

  13. Another common cause of this error on the Mac is Apple's quarantine flag.

    ls the directory containing the resource(s) in question. If you see the extended attribute indicator, i.e., the little @ symbol at the end of the permissions block (e.g. -rw-r--r--@ ) then the file could be quarantined.

    Try ls -la@e and look for com.apple.quarantine

    The following command will remove the quarantine:

    xattr -d com.apple.quarantine /path/to/file

  14. There seem to be many things that cause this. For me it was a lowercase rewrite rule in IIS. Changed the problem files (js and png) to lowercase and problem went away.

div not scrolling properly with slimScroll plugin

I am using the slimScroll plugin for jQuery by Piotr Rochala Which is a great plugin for nice scrollbars on most browsers but I am stuck because I am using it for a chat box and whenever the user appends new text to the boxit does scroll using the .scrollTop() method however the plugin's scrollbar doesnt scroll with it and when the user wants to look though the chat history it will start scrolling from near the top. I have made a quick demo of my situation http://jsfiddle.net/DY9CT/2/ Does anyone know how to solve this problem?

Why does this javascript based printing cause Safari to refresh the page?

The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
