You just need to encode special characters like that before passing them as part of the URL, so `@` would need to be passed as `%40`, eg:

```
https://user:password%40www.example.com
```

In a Master-Detail app I&#39;d like to display a TableView with 5 sections titled:

 1. Your Move
 2. Their Move
 3. Won Games
 4. Lost Games
 5. Options

So I create a blank Master-Detail app in Xcode 5.0.2 and then in its MasterViewController.m (which is a UITableViewController) I&#39;m trying to implement the method:

    - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
        return _titles[section];
    }

**My question** is however how to init the NSArray _titles?

I&#39;m trying in the MasterViewController.m:

    #import &quot;MasterViewController.h&quot;
    #import &quot;DetailViewController.h&quot;
    
    static NSArray *_titles_1 = @[
        @&quot;Your Move&quot;,
        @&quot;Their Move&quot;,
        @&quot;Won Games&quot;,
        @&quot;Lost Games&quot;,
        @&quot;Options&quot;
    ];
    
    @interface MasterViewController () {
        NSMutableArray *_games;
        
        NSArray *_titles_2 = @[
                             @&quot;Your Move&quot;,
                             @&quot;Their Move&quot;,
                             @&quot;Won Games&quot;,
                             @&quot;Lost Games&quot;,
                             @&quot;Options&quot;
        ];
    }
    @end
    
    @implementation MasterViewController
    
    - (void)awakeFromNib
    {
        if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
            self.clearsSelectionOnViewWillAppear = NO;
            self.preferredContentSize = CGSizeMake(320.0, 600.0);
        }
        [super awakeFromNib];
    }
    
    - (void)viewDidLoad
    {
         ....
    }

but both tries above give me syntax errors:

**UPDATE:**

To my surprise there are many suggestions for this simple question, but as an iOS/Objective-C newbie I&#39;m not sure, which solution is most appropriate.

`dispatch_once` - isn&#39;t it a runtime operation to execute something once in a multi-threaded app? Isn&#39;t it overkill here? I was expecting a compile-time solution for initiating a const array...

`viewDidLoad` - when my app changes between background and foreground, wouldn&#39;t it unnecessary initiate my const array again and again?

Shouldn&#39;t I better set the `NSArray` in `awakeFromNib` (since I use stroyboard scenes for all my ViewControllers)? Or maybe in `initSomething` (is the correct method `initWithStyle`?)

Static NSArray of strings - how/where to initialize in a View Controller

I&#39;m trying to set up some selenium tests to our staging server using Sauce Labs. It&#39;s behind a basic http auth, so theoretically I could set the selenium URL to `http://user:password@www.stagesite.com`. *However,* the password contains a &quot;@&quot;, causing all sorts of problems as you can imagine. I tried escaping it with a backslash but that did nothing from what I can tell.

So,

1. is there an alternative way to do http authentication using selenium, i.e., not via the URL. Or,

2. is there a way to use URL-based auth but somehow tell the browser that the &quot;@&quot; is part of the password?

I was asked to build a site , and one of the co-developer told me That I would  need to include the keep-alive header.


Well I read alot about it and still I have questions.

[msdn -&gt;][1]

&gt; The open connection improves performance when a client makes multiple
&gt; requests for Web page content, because the server can return the
&gt; content for each request more quickly. Otherwise, the server has to
&gt; open a new connection for every request



Looking at 

 ![enter image description here][2]

* When The IIS (F) sends `keep alive` header (*or user sends keep-alive*)  , does it mean that (`E`,`C`,`B`) save a connection which is only for my session ? 
* Where does this info is kept ( *&quot;this connection belongs to &quot;Royi&quot;*) ?
* Does it mean that no one else can use that connection
* If so - does it mean that keep alive-header - reduce the number of overlapped connection users ?
* if so , for how long does the connection is saved to me ? (in other words  , if I set keep alive- &quot;keep&quot; till when?)

  p.s. for those who interested : 

clicking [*this sample page*][3] will return keep alive header

Keep-alive header clarification

I have always been trying to avoid using most of the HTTP protocol&#39;s properties for the sake of fear of the unknown.

However, I said to myself that I&#39;m going to face fear today and start using headers purposefully. I have been trying to send `json` data to the browser and use it right away. For example, if I have an Ajax handler function on ready state 4 which looks like so:

    function ajaxHandler(response){
        alert(response.text);
    }

And I have set the content-type header in my PHP code:

    header(&#39;Content-Type: application/json&#39;);
    echo json_encode(array(&#39;text&#39; =&gt; &#39;omrele&#39;));

Why can&#39;t I directly access the property from the handler function, when the browser is clearly told that the incoming data is `application/json`?



HTTP Content-Type Header and JSON

While using the [`requests` module](http://requests.readthedocs.org/en/latest/), is there any way to print the raw HTTP request? 

I don&#39;t want just the headers, I want the request line, headers, and content printout. Is it possible to see what ultimately is constructed from HTTP request?

Python requests - print entire http request (raw)?

&gt; Keep-alives were added to HTTP to basically reduce the significant
&gt; overhead of rapidly creating and closing socket connections for each
&gt; new request. The following is a summary of how it works within HTTP
&gt; 1.0 and 1.1:
&gt; 
&gt;   HTTP 1.0 	The HTTP 1.0 specification does not really delve into how
&gt; Keep-Alive should work. Basically, browsers that support Keep-Alive
&gt; appended an additional header to the request as [edited for clarity] explained below:
&gt; 
&gt;   When the server processes the request and
&gt; generates a response, it also adds a header to the response:
&gt;
&gt;   **Connection: Keep-Alive** 	
&gt;
&gt; When this is done, the socket connection is
&gt; not closed as before, but kept open after sending the response. When
&gt; the client sends another request, it reuses the same connection. The
&gt; connection will continue to be reused until either the client or
&gt; the server decides that the conversation is over, and one of them drops the connection.

The above explanation [comes from here][1]. But I don&#39;t understand one thing 

&gt; When this is done, the socket connection is not closed as before, but
&gt; kept open after sending the response.

As I understand we just send tcp packets to make requests and responses, how this `socket connection` helps and how does it work? We still have to send packets, but how can it somehow establish the persistent connection? It seems so unreal.

Explain http keep-alive mechanism

I am trying to stream a `csv` file from a node.js server. The server portion is very simple :

    server.get(&#39;/orders&#39; function(req, res) {
      res.setHeader(&#39;content-type&#39;, &#39;text/csv&#39;);
      res.setHeader(&#39;content-disposition&#39;, &#39;attachment; filename=&#39;orders.csv&#39;);
      return orders.pipe(res); // assuming orders is a csv file readable stream (doesn&#39;t have to be a stream, can be a normal response)
    }

In my angular controller I am trying to do something like this 

    $scope.csv = function() {
        $http({method: &#39;GET&#39;, url: &#39;/orders&#39;});
    };

This function is called when there&#39;s a click on a button with `ng-click` in my view :

    &lt;button ng-click=&quot;csv()&quot;&gt;.csv&lt;/button&gt;

I have looked at other answers about downloading files from server in Angular, but didn&#39;t find anything that worked for me. Is there a common way to do this ? Seems like something that should be simple.

I have a curious case where the selenium chrome driver `getText()` method (java) returns an empty string for some elements, even though it returns a non-empty string for other elements with the same `xpath`.  Here is a bit of the page.

    &lt;div __gwt_cell=&quot;cell-gwt-uid-223&quot; style=&quot;outline-style:none;&quot;&gt;
    &lt;div&gt;Text_1&lt;/div&gt;
    &lt;div&gt;Text_2&lt;/div&gt;
    &lt;div&gt;Text_3&lt;/div&gt;
    &lt;div&gt;Text_4&lt;/div&gt;
    &lt;div&gt;Text_5&lt;/div&gt;
    &lt;div&gt;Text_6&lt;/div&gt;
    &lt;/div&gt;

for each of the inner &lt;div&gt; tags, I can get valid return values for `getTagName()`, `getLocation()`, `isEnabled()`, and `isDisplayed()`.  However, getText() returns an empty string for some of the divs.  

Further, I notice that if I use the mac chrome driver, it is consistently the ‘&lt;div&gt;Text_5&lt;/div&gt;’ for which `getText()` returns an empty string.  If I use the windows chrome driver, it is , it is consistently the ‘&lt;div&gt;Text_2&lt;/div&gt;’ for which `getText()` returns an empty string.  If I use the firefox driver, `getText()` returns the expected text from all the divs.

Has anyone else had this difficulty?

In my code, I use something like this…

    ArrayList&lt;WebElement&gt; list = (ArrayList&lt;WebElement&gt;) driver.findElements(By.xpath(“my xPath here”));
    for (WebElement e: list) System.out.println(e.getText());

As suggested below, here is the actual `xPath` I am using.  The page snippet above deals with the last two divs.

    //*[@class=&#39;gwt-DialogBox&#39;]//tr[contains(@class,&#39;data-grid-table-row&#39;)]//td[contains(@class,&#39;lms-assignment-selection-wizard-cell&#39;)]/div/div




getText() method of selenium chrome driver sometimes returns an empty string

I&#39;m trying to make Selenium wait for an element that is dynamically added to the DOM after page load. Tried this:

    fluentWait.until(ExpectedConditions.presenceOfElement(By.id(&quot;elementId&quot;));

*In case it helps, here is `fluentWait`:*

    FluentWait fluentWait = new FluentWait&lt;&gt;(webDriver) {
        .withTimeout(30, TimeUnit.SECONDS)
        .pollingEvery(200, TimeUnit.MILLISECONDS);
    }

But it throws a `NoSuchElementException` - looks like `presenceOfElement` expects the element to be there so this is flawed. This must be bread and butter to Selenium and don&#39;t want to reinvent the wheel... could anyone suggest an alternative, ideally without rolling my own `Predicate`?

I&#39;m using Selenium to run tests in Chrome via the Python API bindings, and I&#39;m having trouble figuring out how to configure Chrome to make the `console.log` output from the loaded test available.  I see that there are `get_log()` and `log_types()` methods on the WebDriver object, and I&#39;ve seen https://stackoverflow.com/questions/18261338/get-chromes-console-log/18283831#18283831 which shows how to do things in Java.  But I don&#39;t see an equivalent of Java&#39;s `LoggingPreferences` type in the Python API.  Is there some way to accomplish what I need?

It looks like implementing basic HTTP authentication with Express v3 was trivial:

    app.use(express.basicAuth(&#39;username&#39;, &#39;password&#39;));

Version 4 (I&#39;m using 4.2) removed the `basicAuth` middleware, though, so I&#39;m a little stuck. I have the following code, but it doesn&#39;t cause the browser to prompt the user for credentials, which is what I&#39;d like (and what I imagine the old method did):

    app.use(function(req, res, next) {
        var user = auth(req);
        
        if (user === undefined || user[&#39;name&#39;] !== &#39;username&#39; || user[&#39;pass&#39;] !== &#39;password&#39;) {
            res.writeHead(401, &#39;Access invalid for user&#39;, {&#39;Content-Type&#39; : &#39;text/plain&#39;});
            res.end(&#39;Invalid credentials&#39;);
        } else {
            next();
        }
    });
