At the top of Chrome&#39;s inspector (in the `Network` tab) is a checkbox which says `Preserve log`. Enable this option. Now it doesn&#39;t matter at all how the page navigates, the inspector will keep all log history -- including the redirect response.

## Older versions of Chrome

At the bottom of Chrome&#39;s inspector (in the `Network` tab) is a button with a big circle. Hover over this button and a tooltip says `Preserve log upon navigation`. Click the button and it will turn red. Now it doesn&#39;t matter at all how the page navigates, the inspector will keep all log history -- including the redirect response.

I had the same issue and found the solution differed slightly to previous answers.

I had to select Other for the document type in the filter bar, as well as have preserve log ticked and record network log on.

In Chrome&#39;s developer tools - select &quot;Resources&quot; - then under either &quot;Documents&quot; or &quot;Other&quot; you should be able to find the original request- view the &quot;Headers&quot; to see status code of 301.  There&#39;s a great article here - http://www.html5rocks.com/tutorials/developertools/part1/#toc-resources

I have the following code to take a video as a raw resource, start the video and loop it but I need the video to loop seamlessly as of now when it comes to an end of the clip and starts the clip again the transition between causes a flicker for a split second, which I really can&#39;t have for my app. 

    public class Example extends Activity {
    	VideoView vv;
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            
            vv = (VideoView)findViewById(R.id.VideoView01);

            //Video Loop
            vv.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                public void onCompletion(MediaPlayer mp) {
                    vv.start(); //need to make transition seamless.
                }
            });

            Uri uri = Uri.parse(&quot;android.resource://com.example/&quot;
                    + R.raw.video);
            
            vv.setVideoURI(uri);
            vv.requestFocus();    
            vv.start();
        }
    }

The clip is only 22 seconds long but was created to be seamless so it is possible to work without the delay.

I have Windows 7 (32-bit) installed on laptop.

I downloaded WAMP server and installed it with it&#39;s default options.

However, I noticed that Apache does not work (while MySQL does work!). 

I tried to install it via `Apache → Service → Install Service` and got a message saying that port 80 is taken by Skype. I turned off Skype, and then Apache started to work.

How can I avoid this conflict and allow WAMP and Skype to work simultaneously?

Should I configure Apache to work with other port? Where?

I&#39;m trying to find out of a certain link shorteners and out.php linkscripts redirect using 301 redirect or not. I&#39;m looking at the resources tab in Chrome&#39;s developer tools, but it only shows headers for the target page and not for the link scripts itself.

Also, some of the sites I&#39;m investigating actually redirect more than once, so it&#39;d be best if I could track the entire redirect path.

How can I see if how I was exactly redirected, and if they were using 301 or not?

I want to test some URLs in a web application I&#39;m working on. For that I would like to manually create HTTP POST requests (meaning I can add whatever parameters I like).

Is there any functionality in Chrome and/or Firefox that I&#39;m missing?



How to manually send HTTP POST requests from Firefox or Chrome browser

I&#39;ve got the following...

    chrome.extension.sendRequest({
	  req: &quot;getDocument&quot;,
	  docu: pagedoc,
	  name: &#39;name&#39;
	}, function(response){
	  var efjs = response.reply;
	});

which calls the following..


    case &quot;getBrowserForDocumentAttribute&quot;:
	  alert(&quot;ZOMG HERE&quot;);
	  sendResponse({
	    reply: getBrowserForDocumentAttribute(request.docu,request.name)
	  });
      break;

However, my code never reaches &quot;ZOMG HERE&quot; but rather throws the following error while running `chrome.extension.sendRequest`

     chromeHidden.JSON.stringify
     chrome.Port.postMessage

When trying to do a HTTP request using XMLHttpRequest from a local file, it basically fails due to `Access-Control-Allow-Origin` violation.

However, I&#39;m using the local web page myself, so I was wondering if there is any way to make Google Chrome allow these requests, which are from a local file to a URL on the Internet.

E.g., `$.get(&#39;http://www.google.com/&#39;)` fails when executing in a local file, but I&#39;ve scripted the page myself and I&#39;m using it myself, so it would be extremely useful if I could suppress it and load the URL.

So, how can I allow Google Chrome to load URLs using XMLHttpRequest from local files?

I am creating an extension that will download a mp3 file off a website. I am trying to do this by creating a new tab with the link to the mp3 file, but chrome keeps opening it inside the player instead of downloading it. Is there any way I can create a pop-up to ask the user to &quot;save-as&quot; the file?

How do you redirect to a page from another page with JavaScript?



How do I redirect with JavaScript?

The differences between the various HTTP 3XX redirect codes are not clear to me.  Yes, I&#39;ve read the spec, but there seems to be some discrepancy between the standard and actual practice here.

The `301` redirect code seems clear enough: This means the resource was permanently moved to another URI, and future requests should use that URI.

And the `307` redirect code also seems clear: it means the redirect is temporary, and future requests should still use the original URI.

But I can&#39;t tell what the difference is between `302` and `303`, or why either of them are really different from `301`.  It seems that `302` was originally intended to be a *temporary* redirect, (like `307`), but in practice, most browsers treated it like a `303`.  But what&#39;s the difference between a `303` and a `301`?  Is `301` supposed to mean the redirect is *more* permanent?

I want to redirect requests on two conditions using nginx. 

This doesn&#39;t work:

      if ($host = &#39;domain.com&#39; || $host = &#39;domain2.com&#39;){
        rewrite ^/(.*)$ http://www.domain.com/$1 permanent;
      }   

What is the correct way to do this?



nginx.conf redirect multiple conditions

I want to redirect the Index action of the Home controller to another controller&#39;s action and nothing else. My code is thus:

        public void Index()
        {
            //All we want to do is redirect to the class selection page
            RedirectToAction(&quot;SelectClasses&quot;, &quot;Registration&quot;);
        }

Right now, this just loads a 0 kB blank page and does nothing. I have a feeling it has something to do with that void return type, but I don&#39;t know what else to change it to. What&#39;s the issue here?

How to redirect HTTP to HTTPS in MVC application (IIS7.5)

I have a php script that returns just plain text **without** any html. Now I want to make a cURL request to that script and I get the following response:

    HTTP/1.1 200 OK
    Date: Mon, 28 Feb 2011 14:21:51 GMT
    Server: Apache/2.2.14 (Ubuntu)
    X-Powered-By: PHP/5.2.12-nmm2
    Vary: Accept-Encoding
    Content-Length: 6
    Content-Type: text/html
    
    6.8320

The actuall response is just **6.8320** as text without any html. I want to retrieve it from the response above by just removing the header information.

I already minified the script a bit:

    $url = $_GET[&#39;url&#39;];
    
    if ( !$url ) {
      
      // Passed url not specified.
      $contents = &#39;ERROR: url not specified&#39;;
      $status = array( &#39;http_code&#39; =&gt; &#39;ERROR&#39; );
      
    } else if ( !preg_match( $valid_url_regex, $url ) ) {
      
      // Passed url doesn&#39;t match $valid_url_regex.
      $contents = &#39;ERROR: invalid url&#39;;
      $status = array( &#39;http_code&#39; =&gt; &#39;ERROR&#39; );
      
    } else {
      $ch = curl_init( $url );
      
      if ( strtolower($_SERVER[&#39;REQUEST_METHOD&#39;]) == &#39;post&#39; ) {
        curl_setopt( $ch, CURLOPT_POST, true );
        curl_setopt( $ch, CURLOPT_POSTFIELDS, $_POST );
      }
      
      curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
      curl_setopt( $ch, CURLOPT_HEADER, true );
      curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
      
      curl_setopt( $ch, CURLOPT_USERAGENT, $_GET[&#39;user_agent&#39;] ? $_GET[&#39;user_agent&#39;] : $_SERVER[&#39;HTTP_USER_AGENT&#39;] );
    
      list( $header, $contents ) = preg_split( &#39;/([\r\n][\r\n])\\1/&#39;, curl_exec( $ch ), 2 );
      
      $status = curl_getinfo( $ch );
      
      curl_close( $ch );
    }
    
    // Split header text into an array.
    $header_text = preg_split( &#39;/[\r\n]+/&#39;, $header );
    
    if ( true ) {
      if ( !$enable_native ) {
        $contents = &#39;ERROR: invalid mode&#39;;
        $status = array( &#39;http_code&#39; =&gt; &#39;ERROR&#39; );
      }
      
      // Propagate headers to response.
      foreach ( $header_text as $header ) {
        if ( preg_match( &#39;/^(?:Content-Type|Content-Language|Set-Cookie):/i&#39;, $header ) ) {
          header( $header );
        }
      }
      print $contents;
    }

Any idea what I need to change to remove the header information from the response?

How to remove HTTP headers from CURL response?

In a blog post I use the following PHP to set the content-type of a response:

    header(&#39;content-type: application/json; charset=utf-8&#39;);

I just got a comment on that post saying that `content-type` needs to be capitalized, `Content-type`. Is this correct? It seems to work for me with all lower-case, and I assumed the HTTP headers were case-insensitive. Or does it just work because browsers are nice?

Are HTTP headers case-sensitive?

I am working with an embedded platform that has 16MB of RAM only. And I need to deep packet filter HTTP streams. To prevent a Denial of Service attack on the device I&#39;d like some statistical averages regarding HTTP stream sizes, specifically the HTTP header in particular.

What is the average size of an HTTP request/response header?

I&#39;m implementing a REST service in PHP. This service should be able to support multiple input and output formats (JSON, XML). For that reason I want to check the request headers *&quot;Accept&quot;* and *&quot;Content-Type&quot;* for the type of content sent and requested by the client.

Accessing the *&quot;Accept&quot;* header is a simple as using `$_SERVER[&#39;HTTP_ACCEPT&#39;]`. But accessing the *&quot;Content-Type&quot;* header seems to be a difficult task. I searched the PHP documentation and the web, but the only solution offered was the use of the PHP function `apache_request_headers()` which is only supported when PHP is installed as an Apache module, which is not true in my case.

So my question now: How can I access the header &quot;Content-Type&quot; of a request?

Get &quot;Content-Type&quot; header of request in PHP

I&#39;m using `Pattern`/`Matcher` to get the response code in an HTTP response. `groupCount` returns 1, but I get an exception when trying to get it! Any idea why?

Here&#39;s the code:

    //get response code
    String firstHeader = reader.readLine();
    Pattern responseCodePattern = Pattern.compile(&quot;^HTTP/1\\.1 (\\d+) OK$&quot;);
    System.out.println(firstHeader);
    System.out.println(responseCodePattern.matcher(firstHeader).matches());
    System.out.println(responseCodePattern.matcher(firstHeader).groupCount());
    System.out.println(responseCodePattern.matcher(firstHeader).group(0));
    System.out.println(responseCodePattern.matcher(firstHeader).group(1));
    responseCode = Integer.parseInt(responseCodePattern.matcher(firstHeader).group(1));

And here&#39;s the output:

    HTTP/1.1 200 OK
    true
    1
