Use `window.location.protocol` to check if it is `https:`

    function isSecure()
    {
       return window.location.protocol == &#39;https:&#39;;
    }

Alternatively you can omit specifying &quot;window&quot; if you don&#39;t have a locally scoped location.

    function isSecure()
    {
       return location.protocol == &#39;https:&#39;;
    }

As google analytics taught me:

    if (&quot;https:&quot; == document.location.protocol) {
    	/* secure */
    } else {
    	/* unsecure */
    }

Second method for newest browsers: 

    var secure = window.isSecureContext;

or just get isSecureContext:

    if (isSecureContext) {
       ...
    }

I have been involved in a lot of projects, both old and new, and one thing that they have in common is that almost none of them have been using unit testing. I prefer to use it, but often the customer isn&#180;t ready to pay for that, and suppose that the code just works as it should.

So, do you use unit testing in your projects, or do you rely on your coding skills?

Are you really using unit tests?

I have noticed that our VMWare VMs often have the incorrect time on them. No matter how many times I reset the time they keep on desyncing.

Has anyone else noticed this? What do other people do to keep their VM time in sync?

Is it possible to detect, on the client side, whether the user is using an encrypted page or not?

Put another way -- I want to know if the URL of the current page starts with http or https.



How can I use JavaScript on the client side to detect if the page was encrypted?

If I have a list like this:

    &lt;ul id=&quot;mylist&quot;&gt;
        &lt;li id=&quot;list-item1&quot;&gt;text 1&lt;/li&gt;
        &lt;li id=&quot;list-item2&quot;&gt;text 2&lt;/li&gt;
        &lt;li id=&quot;list-item3&quot;&gt;text 3&lt;/li&gt;
        &lt;li id=&quot;list-item4&quot;&gt;text 4&lt;/li&gt;
    &lt;/ul&gt;

What&#39;s the easiest way to re-arrange the DOM nodes to my preference? (This needs to happen automatically when the page loads, the list-order preference is gained from a cookie)

E.g.


    &lt;ul id=&quot;mylist&quot;&gt;
        &lt;li id=&quot;list-item3&quot;&gt;text 3&lt;/li&gt;
        &lt;li id=&quot;list-item4&quot;&gt;text 4&lt;/li&gt;
        &lt;li id=&quot;list-item2&quot;&gt;text 2&lt;/li&gt;
        &lt;li id=&quot;list-item1&quot;&gt;text 1&lt;/li&gt;
    &lt;/ul&gt;



Easiest way to sort DOM nodes?

If for example you follow the link:

`data:application/octet-stream;base64,SGVsbG8=`

The browser will prompt you to download a file consisting of the data held as base64 in the hyperlink itself.  Is there any way of suggesting a default name in the markup?  If not, is there a JavaScript solution?


Is there any way to specify a suggested filename when using data: URI?

Let&#39;s say I have an html form.  Each input/select/textarea will have a corresponding `&lt;label&gt;` with the `for` attribute set to the id of it&#39;s companion. In this case, I know that each input will only have a single label.

Given an input element in javascript &amp;mdash; via an onkeyup event, for example &amp;mdash; what&#39;s the best way to find it&#39;s associated label?

I have a suspicion that I&#39;m using the `finally` block incorrectly, and that I don&#39;t understand the fundamentals of its purpose...

     function myFunc() {
          try {
               if (true) {
                    throw &quot;An error&quot;;
               }
          } catch (e) {
               alert (e);
               return false;
          } finally {
               return true;
          }
     }

This function will run the `catch` block, alert &quot;An error&quot;, but then return true. Why doesn&#39;t it return false?

Javascript error handling with try .. catch .. finally

I&#39;m automating a web application (the Mantis bug tracker) and I&#39;m getting an interesting response header from it, called Refresh:

    HTTP/1.x 200 OK
    ...
    Refresh: 0;url=my_view_page.php

It seems to be acting the same way that [meta refresh][1] does, and the meta refresh technique implies that it is an equivalent of a header in HTTP.

Problem is, I can&#39;t find any mention of the Refresh header in the [HTTP standard][2] or any other definitive documentation on how it should be parsed and what the browser should do when it encounters it.

What&#39;s going on here?

I&#39;m trying to test the functionality of a web app by scripting a login sequence in Python, but I&#39;m having some troubles.

Here&#39;s what I need to do:

1. Do a POST with a few parameters and headers.
2. Follow a redirect
3. Retrieve the HTML body.

Now, I&#39;m relatively new to python, but the two things I&#39;ve tested so far haven&#39;t worked. First I used httplib, with putrequest() (passing the parameters within the URL), and putheader(). This didn&#39;t seem to follow the redirects.

Then I tried urllib and urllib2, passing both headers and parameters as dicts. This seems to return the login page, instead of the page I&#39;m trying to login to, I guess it&#39;s because of lack of cookies or something.

Am I missing something simple?

Thanks.

I&#39;d like some advice on designing a REST API which will allow clients to add/remove large numbers of objects to a collection efficiently.

Via the API, clients need to be able to add items to the collection and remove items from it, as well as manipulating existing items. In many cases the client will want to make bulk updates to the collection, e.g. adding 1000 items and deleting 500 different items. It feels like the client should be able to do this in a single transaction with the server, rather than requiring 1000 separate POST requests and 500 DELETEs. 

Does anyone have any info on the best practices or conventions for achieving this?

My current thinking is that one should be able to PUT an object representing the change to the collection URI, but this seems at odds with the [HTTP 1.1 RFC][1], which seems to suggest that the data sent in a PUT request should be interpreted independently from the data already present at the URI. This implies that the client would have to send a complete description of the new state of the collection in one go, which may well be very much larger than the change, or even be more than the client would know when they make the request.

Obviously, I&#39;d be happy to deviate from the RFC if necessary but would prefer to do this in a conventional way if such a convention exists.

Bulk Collection Manipulation through a REST (RESTful) API

I have a site that connects using cURL (latest version) to a secure gateway for payment.

The problem is cURL always returns 0 length content. I get headers only. And only when I set cURL to return headers. I have the following flags in place.

    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_URL, $gatewayURI);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($ch, CURLOPT_POST, 1);

The header returned is

    HTTP/1.1 100 Continue
    
    HTTP/1.1 200 OK
    Date: Tue, 25 Nov 2008 01:08:34 GMT
    Server: Microsoft-IIS/6.0
    X-Powered-By: ASP.NET
    Content-Length: 0
    Content-Type: text/html
    Set-Cookie: ASPSESSIONIDxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx; path=/
    Cache-control: private

I have also tried cURL&#39;ing different sites and they return content fine. I think the problem might have something to do with the https connection.

I have spoken with the company and they are unhelpful.

Has anyone else experienced this error and know a work around? Should I ditch cURL and try and use `fsockopen()` ?

Thank you. :)



Can&#39;t connect to HTTPS site using cURL. Returns 0 length content instead. What can I do?

I am creating a secure web based API that uses HTTPS; however, if I allow the users to configure it (include sending password) using a query string will this also be secure or should I force it to be done via a POST?

Is a HTTPS query string secure?

I want to know if the page is being accessed via http or https using JavaScript.  Is there some sort of isSecure() method, or should I just parse it out of the URL somehow?

How do I determine whether a page is secure via JavaScript?

When sending the user to a checkout page, they are switched from `http://sitename.com` to `https://sitename.com`.

 As a result, `$_SESSION` variables are lost.

The site has a valid SSL certificate which may or may not be of some use.

Session lost when switching from HTTP to HTTPS in PHP

Are all URLs encrypted when using TLS/SSL (HTTPS) encryption? I would like to know because I want all URL data to be hidden when using TLS/SSL (HTTPS).

If TLS/SSL gives you total URL encryption then I don&#39;t have to worry about hiding confidential information from URLs.
