this should do it:

http://en.wikipedia.org/wiki/Mozilla

&gt; When users visit a website (via a user agent such as a web browser), a
&gt; text string is generally sent to identify the user agent to the web
&gt; server. It is known as the &quot;user agent string&quot;. The Netscape web
&gt; browser identified itself as &quot;Mozilla/&lt;version&gt;&quot; followed by some
&gt; information about the operating system it was running on.
&gt; 
&gt; Because the Netscape browser initially implemented many features not
&gt; available in other browsers and quickly came to dominate the market, a
&gt; number of web sites were designed to work, or work fully, only when
&gt; they detected an appropriate version of Mozilla in the user agent
&gt; string. Thus, competing browsers began to emulate (&quot;cloak&quot; or &quot;spoof&quot;)
&gt; this string in order to also work with those sites. The earliest
&gt; example of this is Internet Explorer&#39;s use of a user agent string
&gt; beginning &quot;Mozilla/&lt;version&gt; (compatible; MSIE &lt;version&gt;...&quot;, in order
&gt; to receive content intended for Netscape, its main rival at the time
&gt; of its development. This format of user agent string has since been
&gt; copied by other user agents, and persisted even after Internet
&gt; Explorer came to dominate the browser market.

[HandlerInterceptor][1]s in Spring can now be configured to be invoked only on certain URLs using `&lt;mvc:interceptors&gt;`.

Servlet Filters can achieve same functionality (logging, security etc). So which one should be used?

I think with Interceptors, one can use `ModelAndView` object to work with Models so it has more advantages. Can anyone draw out scenarios where Filters or Interceptors have advantages over the other?

Why does Internet Explorer has `Mozilla` in UserAgent?

In Firefox it&#39;s stating:

&gt;Mozilla/5.0 (Windows NT 6.1; rv:7.0.1) Gecko/20100101 Firefox/7.0.1

In Interner Explorer it&#39;s stating:

In some blogs/forums it&#39;s mentioned, that it is due to some historical reasons, but what&#39;s the reason?

It would be very helpful to know about it.

Lots of articles in the web like this : http://www.fontspring.com/blog/fixing-ie9-font-face-problems suggest to add a `?#iefix`to the eot url. I was curious to know *how* is this going to solve the problem. Thanks.

I&#39;m using the following code, but having it fail in IE.
The message is:

&gt;Unable to get value of the property &#39;add&#39;: object is null or undefined&quot;

I assume this is just an IE support issue. How would you make the following code work in IE?

Any ideas?

    var img = new Image();
    img.src = &#39;/image/file.png&#39;;
    img.title = &#39;this is a title&#39;;
    img.classList.add(&quot;profilePic&quot;);
    var div = document.createElement(&quot;div&quot;);
    div.classList.add(&quot;picWindow&quot;);
    div.appendChild(img);
    content.appendChild(div);

I need to use foursquare API to search venues. Of course it is cross-domain. 

It has no any problems in Firefox but in Internet Explorer (7, 8, 9 I&#39;ve tested).

My javascript code looks like:

    searchVenues: function(searchQuery) {
        $.ajax({
           url: &#39;https://api.foursquare.com/v2/venues/search&#39;,
           data: {
                sw: bound_south_west,
                ne: bound_north_east,
                query: searchQuery.query,
                oauth_token: FSQ_OAUTH_TOKEN,
                limit: 25,
                intent: &#39;browse&#39;,
                v: 20120206
           },
           cache: false,
           dataType: &#39;json&#39;,
           success: function(data) {
               displayResults(data, searchQuery.query);
           },
           error: function(xhr, status, errorThrown) {
               console.log(errorThrown+&#39;\n&#39;+status+&#39;\n&#39;+xhr.statusText);
           }
        });
    }

In Firefox, it perfectly displays received data.
In Internet Explorer, it logs on console:

    No Transport
    Error
    Error

What should I do?

I created animation in flash and converted it into HTML5 using [Swiffy](http://www.google.com/doubleclick/studio/swiffy/).

I think it&#39;s using SVG to render all of it; is there some JavaScript or a trick to make IE8 and below support it? My animation is working well with Internet Explorer 9.

Thanks!

This function works fine. It scrolls the body to a desired container&#39;s offset

    function scrolear(destino){
    	var stop = $(destino).offset().top;
    	var delay = 1000;
    	$(&#39;body&#39;).animate({scrollTop: stop}, delay);
    	return false;
    }

But not in Firefox. Why?

-EDIT-

To handle de double trigger in the accepted answer, I suggest stoping the element before the animation:

    $(&#39;body,html&#39;).stop(true,true).animate({scrollTop: stop}, delay);

How come I get this message from Firefox Web Console

I *DO* know this question has been asked at least a thousand times in this website alone, but I HAVE read many of those threads, I DO consider myself very knowledgeable and rarely ever ask anything, instead prefer to do my own research.

However, THIS issue is so strange, without hope for real enlightenment (since this question HAS been discussed so often and still I could not benefit from reading there), here is my issue:

favicon.ico exists, and (locally hosted development website) `http://website/favicon.ico` displays the correct icon. Its size is a mere 198 Bytes, so the size limit I found in Firefox&#39;s about:config of 1024 Bytes is adhered to. According to the wisdom on favicons on the web the browser should ask for favicons on its own when there is nothing in the &lt;head&gt; of the page. However, my apache log clearly shows Firefox (9.01) never even asks for it.

Next: when I add 

    &lt;link rel=&quot;shortcut icon&quot; href=&quot;/favicon.ico&quot;&gt;

I still don&#39;t get a favicon.

Next: when I instead use

    &lt;link rel=&quot;shortcut icon&quot; href=&quot;/favicon.ico?&quot;&gt;

(note the trailing &quot;?&quot;) I suddenly *DO* get a favicon. BUt it cannot be a cache issue! First, I have cleared the cache, second, as I mentioned above, I already successfully loaded the icon file into Firefox through its URL `http://website/favicon.ico`

I am unable to explain this behavior of Firefox. Chrome shows the correct favicon, by the way.

This is my page head:

    &lt;!doctype html&gt;
    &lt;html&gt;
    &lt;head&gt;
    	&lt;meta charset=&quot;utf-8&quot;&gt;
        &lt;link rel=&quot;shortcut icon&quot; href=&quot;/favicon.ico?&quot; /&gt;
    &lt;/head&gt;
    ...
As soon as I append at least the &quot;?&quot; after &quot;ico&quot; it works.

Here is what the server sends when the icon is requested, since some have asked for this. **I have no idea why this would be useful, since a) I said my cache was empty for each test (checked with about:cache too), and b) I said the server is never even asked for the file when it does not show up.** Firefox just does not ask without the &quot;?&quot; - with cache empty! The request shows up in the apache log ONLY when I use the appended &quot;?&quot;.

I&#39;d like to get a script that can grab the user&#39;s user agent and prop it to an attribute.

I&#39;m making a website problems contact form and I usually need to know what browser the user is using. How can I detect the user agent string and prop it as the value of an input element.

My html looks something like:

    &lt;input type=&quot;hidden&quot; id=&quot;UserAgent&quot; name=&quot;User Agent&quot; /&gt;

I want the user agent to be added to that as the value attribute so it would look like:

    &lt;input type=&quot;hidden&quot; id=&quot;UserAgent&quot; name=&quot;User Agent&quot; value=&quot;Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/534.53.11 (KHTML, like Gecko) Version/5.1.3 Safari/534.53.10&quot; /&gt;

How to get user agent in PHP

I want to bounce users of our web site to an error page if they&#39;re using a version of `Internet Explorer` prior to v9. It&#39;s just not worth our time and money to support `IE pre-v9`. Users of all other non-IE browsers are fine and shouldn&#39;t be bounced. Here&#39;s the proposed code:

    if(navigator.appName.indexOf(&quot;Internet Explorer&quot;)!=-1){		//yeah, he&#39;s using IE
    	var badBrowser=(
    		navigator.appVersion.indexOf(&quot;MSIE 9&quot;)==-1 &amp;&amp;	//v9 is ok
    		navigator.appVersion.indexOf(&quot;MSIE 1&quot;)==-1	//v10, 11, 12, etc. is fine too
    	);
    						
    	if(badBrowser){
    		// navigate to error page
    	}
    }

Will this code do the trick?

To head off a few comments that will probably be coming my way:

 1. Yes, I know that users can forge their `useragent` string. I&#39;m not concerned.
 2. Yes, I know that programming pros prefer sniffing out feature-support instead of browser-type but I don&#39;t feel this approach makes sense in this case. I already know that all (relevant) non-IE browsers support the features that I need and that all `pre-v9 IE` browsers don&#39;t. Checking feature by feature throughout the site would be a waste.
 3. Yes, I know that someone trying to access the site using `IE v1` (or &gt;= 20) wouldn&#39;t get &#39;badBrowser&#39; set to true and the warning page wouldn&#39;t be displayed properly. That&#39;s a risk we&#39;re willing to take.
 4. Yes, I know that Microsoft has &quot;conditional comments&quot; that can be used for precise browser version detection. IE no longer supports conditional comments as of `IE 10`, rendering this approach absolutely useless.

Any other obvious issues to be aware of?

At times I want to revisit a change I committed to SVN a short while back, but don&#39;t recall the specific files involved or the revision number.  So I would like to see a list of recent commit messages, ideally including the files included in each commit.

I picture going to the root of my working copy and entering something like the following to see the messages and files associated with the most recent 5 commits:

    svn log -l5 -v *

Unfortunately, this command requires a single target, and won&#39;t accept &#39;*&#39;.  I know SVN has the information I want.  Is there a simple way to retrieve it?

How to get a list of all recent SVN commit messages?

I understand it&#39;s off topic, I couldn&#39;t find anywhere online and I was thinking maybe programming gurus in the community might know this.  
I usually use 

    kill -9 pid

to kill the job. I always wondered the origin of 9. I looked it up online, and it says

&quot;9 Means KILL signal that is not catchable or ignorable. In other words it would signal process (some running application) to quit immediately&quot; (source: http://wiki.answers.com/Q/What_does_kill_-9_do_in_unix_in_its_entirety)

But, why 9? and what about the other numbers? is there any historical significance or because of the architecture of Unix?


Why number 9 in kill -9 command in unix?

In the course of my reading I came accross [WG14 Defect Report #51](http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_051.html) written in 1993 (or perhaps 1893, they left off the century and millennium). In the code sample there, apparently an operator spelled `-&gt;&gt;` is used on a pointer to a `struct`. I can&#39;t find it in any operator precedence tables I&#39;ve found, so I am wondering, is or was it ever an operator, and if so, what does (or did, as the case may be) this operator do?

At first I thought it was a typo, but it is reproduced twice more in the text and another time in the code sample in the response to the question, and I have a hard time believing it just slipped past at least two C experts without being noticed, when it jumped out at a novice like me. It&#39;s also at the focal point of the code, very easy to notice, and was never corrected.

Here is the code with added indentation:

    #include &lt;stdlib.h&gt;
    
    struct A {
        char x[1];
    };
    
    main()
    {
        struct A *p = (struct A *) malloc(sizeof(struct A) + 100);
        p-&gt;&gt;x[5] = &#39;?&#39;;  /* This is the key line [for both them and us] */
        return 0;
    }

I tried to compile this code with both a C and C++ compiler and it failed to parse in either one. Perhaps this was some operator in an early version of C that isn&#39;t used any more?

This feels suspiciously like the [What is the name of this operator: &quot;--&gt;&quot;?](https://stackoverflow.com/questions/1642028/what-is-the-name-of-this-operator) question, but I don&#39;t think this is a combination of two other operators, I don&#39;t see how it can be divided up and be valid.

Is this -&gt;&gt; an old operator or a typo/error?

Recently I had to run a command that unfortunately required me to type a password right on the command line.

Afterwards, I cleared my screen with &quot;Clear&quot;, but also wanted to clear the command history so the offending command wouldn&#39;t show up in the session history. Unfortunately, the [Clear-History][1] cmdlet doesn&#39;t seem to actually do what its documentation claims - running Clear-History doesn&#39;t seem to have any impact on the session history whatsoever.

I can still see previous commands in the pop-up history menu, and scroll through old commands by pressing the up key. Here&#39;s a screengrab demonstrating the problem:

![PowerShell clear history failure][2]

I&#39;ve verified with [Get-Command][3] that Clear-History is indeed executing the expected built-in PowerShell cmdlet.

I&#39;ve tried a few variations, such as &quot;Clear-History -count 10 -newest&quot;, all failing to show any effect. When I specify an exact history ID, such as &quot;Clear-History -id 3&quot;, I receive an error like this:

    Clear-History : Cannot locate history for Id 3.

Even if I can see command #3 on the screen.
