There&#39;s only [one registered mediatype][1] for SVG, and that&#39;s the one you listed, `image/svg+xml`. You can of course serve SVG as XML too, though browsers tend to behave differently in some scenarios if you do, for example I&#39;ve seen cases where SVG used in CSS backgrounds fail to display unless served with the `image/svg+xml` mediatype.

I have this in my .htaccess file:

    RewriteCond %{HTTP_HOST} ^example.com$
    RewriteRule (.*) http://www.example.com$1 [R=301,L]

but whenever I access a file on my root like `http://example.com/robots.txt` it will redirect to `http://www.example.comrobots.txt/`.

How can I correct this so that it will redirect correctly to `http://www.example.com/robots.txt`?

What is the difference between non-repeatable read and phantom read?

I have read the [Isolation (database systems) article from Wikipedia](http://en.wikipedia.org/wiki/Isolation_(database_systems)), but I have a few doubts. In the below example, what will happen: the **non-repeatable read** and **phantom read**?

####**Transaction A**

    SELECT ID, USERNAME, accountno, amount FROM USERS WHERE ID=1

####**OUTPUT:**

    1----MIKE------29019892---------5000

####**Transaction B**

    UPDATE USERS SET amount=amount+5000 where ID=1 AND accountno=29019892;
    COMMIT;

####**Transaction A**

    SELECT ID, USERNAME, accountno, amount FROM USERS WHERE ID=1

Another doubt is, in the above example, which isolation level should be used? And why?

This is the usual SVG mime type:

    image/svg+xml
And it works great. However, when embedding an SVG font, chrome tells you the mime type is incorrect, obviously because you return a font instead of an image.

Is there any universal mime type? is chrome wrong? is `application/svg+xml` accepted somehow?

I guess this is still a gray area in HTML5 but someone here might know.

Right mime type for SVG images with fonts embedded

Is it possible for the child of a div set to `pointer-events: none` to have pointer events?


I need the div that holds another div to allow pointer events to pass through, but for the div itself to still have events. 

Is this possible?

Consider this [JSFiddle][1]. It works fine in Firefox (14.0.1), but fails in Chrome (21.0.1180.75), Safari (?) and Opera(12.01?) on both Windows (7) and OS X (10.8). As far as I can tell the issue is with either the `setData()` or `getData()` methods on the `dataTransfer` object. Here&#39;s the relevant code from the JSFiddle.

    var dragStartHandler = function (e) {
        e.originalEvent.dataTransfer.effectAllowed = &quot;move&quot;;
        e.originalEvent.dataTransfer.setData(&quot;text/plain&quot;, this.id);
    };
    
    var dragEnterHandler = function (e) {
        //  dataTransferValue is a global variable declared higher up.
        //  No, I don&#39;t want to hear about why global variables are evil,
        //  that&#39;s not my issue.
        dataTransferValue = e.originalEvent.dataTransfer.getData(&quot;text/plain&quot;);
        
        console.log(dataTransferValue);
    };

As far as I can tell this should work perfectly fine and if you look at the console while dragging an item you will see the id written out, which means that it&#39;s finding the element just fine and grabbing it&#39;s id attribute. The question is, is it just not setting the data or not getting the data?

I&#39;d appreciate suggestions because after a week of working on this with three attempts and some 200+ versions, I&#39;m starting to loose my mind. All I know is it used to work back in version 60 or so and that specific code hasn&#39;t changed at all...

&lt;s&gt;Actually, one of the major differences between 6X and 124 is that I changed the event binding from `live()` to `on()`. I don&#39;t think that&#39;s the issue, but I&#39;ve come to see a couple failures from Chrome when it comes to DnD while working on this.&lt;/s&gt; This has been debunked. The event binding method has no effect on the issue.

**UPDATE**

I&#39;ve created a new [JSFiddle][2] that strips out absolutely everything and just leaves the event binding and handlers. I tested it with jQuery 1.7.2 and 1.8 with both `on()` and `live()`. The issue persisted so I dropped down a level and removed all frameworks and used pure JavaScript. The issue *still* persisted, so based on my testing it&#39;s not my code that&#39;s failing. Instead it appears that Chrome, Safari and Opera are all implementing either `setData()` or `getData()` off spec or just failing for some reason or another. Please correct me if I&#39;m wrong.

Anyway, if you take a look at the new JSFiddle you should be able to replicate the issue, just look at the console when you&#39;re dragging over an element designated to accept a drop. I&#39;ve gone ahead and opened a ticket with [Chromium][3]. In the end I may still be doing something wrong, but I simply don&#39;t know how else to do DnD at this point. The new JSFiddle is as stripped down as it can get...

I have a graph using force layout, but it has a fixed width `w` and height `h`:

    var svg = d3.select(&quot;#viz&quot;).append(&quot;svg&quot;)
                .attr(&quot;id&quot;, &quot;playgraph&quot;)
                .attr(&quot;width&quot;, w)
                .attr(&quot;height&quot;, h)
    
    var force = d3.layout.force()
                  .nodes(nodes)
                  .links(links)
                  .charge(-1600)
                  .linkDistance(45)
                  .size([w, h]); 

which results in a svg graph that does not scale or down despite of changes in screen or browser window size. In order to make it responsive (i.e. automatically resizes itself), I tried using `viewBox` and `preserveAspectRatio` attributes:

    var svg = d3.select(&quot;#viz&quot;).append(&quot;svg&quot;)
                .attr(&quot;id&quot;, &quot;playgraph&quot;)
                .attr(&quot;width&quot;, w)
                .attr(&quot;height&quot;, h)
                .attr(&quot;viewBox&quot;, &quot;0, 0, 600, 400&quot;)
                .attr(&quot;preserveAspectRatio&quot;, &quot;xMidYMid meet&quot;);

Unfortunately, this didn&#39;t work as nothing happens when I adjust the browser window size. I wonder if the `.size([w, h])` of the force graph has anything to do with this.

Please shed some light on how to use `viewBox` and `preserveAspectRatio` attributes with force layout graphs.

This is a self Q&amp;A of a handy piece of code I came up with.

Currently, there isn&#39;t an easy way to embed an SVG image and then have access to the SVG elements via CSS. There are various methods of using JS SVG frameworks, but they are overly complicated if all you are doing is making a simple icon with a rollover state.

So here is what I came up with, which I think is by far the easiest way to use SVG files on a website. It takes its concept from the early text-to-image replacement methods, but as far as I am aware has never been done for SVGs.

This is the question:

I need a vector image of a Wikipedia navbox. Unfortunately, Inkscape can&#39;t open the HTML file, and neither Opera nor Chromium can save the page as SVG.

Does anybody how to turn HTML into SVG, either the entire page or a div on the page? I need the styled HTML, CSS and all.

I&#39;m using Font-Awesome, but while the font files are not loaded, the icons appear with .

    }

How do I know that these files have been loaded and I&#39;m finally able to show the icons?

**Edit:**
I&#39;m not talking when the page is loaded (onload), because the font could be loaded before the whole page.

I can&#39;t figure out how to force the MIME type `application/json` for a view in Flask. Here is a simple view I&#39;ve thrown together for demonstration purposes:

    @app.route(&quot;/&quot;)
    def testView():
        ret = &#39;{&quot;data&quot;: &quot;JSON string example&quot;}&#39;
        return ret

The JSON string (held in variable `ret`) is gathered from elsewhere (using stdout from another program using [`subprocess`](http://docs.python.org/library/subprocess.html)) so I can&#39;t use [`jsonify`](http://flask.pocoo.org/docs/api/#flask.jsonify) provided with Flask.

I&#39;ve had a look at the [&quot;Returning Json&quot; Documentation][1] and [this](https://stackoverflow.com/questions/7086448/) Stackoverflow question but I haven&#39;t had any luck so far.

Forcing application/json MIME type in a view (Flask)

For certain resources, my RESTful server only accepts `PUT` and `POST` requests with JSON objects as the content body, thus requiring a `Content-Type` of `application/json` instead of `application/x-www-form-urlencoded` or `multipart/form-data` or anything else.

Malformed JSON (or lack thereof) returns a `400` with the error message taken directly from the exception raised by the JSON parser, for debugging purposes.

Which HTTP error code means that the client sent a request with an unacceptable `Content-Type`, even if the server could technically parse the request content?

I&#39;m getting a &quot;Resource interpreted as Script but transferred with MIME type text/plain&quot; warning in Google Chrome when including a local script file.

I know the problem appears when loading a file from a server or through ajax which most often depends on wrong headers being set.

The weird thing is that I get this warning even though it is run from a local folder: `file:///C:/test/foo.html`

This happens only in Chrome with the most basic html there is:

    &lt;!DOCTYPE html&gt;
        &lt;html&gt;
    	&lt;head&gt;
    		&lt;script type=&quot;text/javascript&quot; src=&quot;bar.js&quot;&gt;&lt;/script&gt;
    	&lt;/head&gt;
    	&lt;body&gt;
    	&lt;/body&gt;
    &lt;/html&gt;

bar.js is also as simple as it can get:
  
    function hello() {}

I&#39;ve tried adding a meta tag: 

    &lt;meta http-equiv=&quot;content-script-type&quot; content=&quot;text/javascript&quot;&gt;

and tested with other doctypes but nothing seems to help.

This obviously isn&#39;t a real issue since the scripts still work fine, but I&#39;m working on a large project and currently have around 150 scripts included. It therefore makes it difficult to see when an actual warning occurs in between them.

Everything works fine when I run the file on a server, locally or remote.

Any ideas on why chrome is annoying me with this?
