Tool for viewing response headers

What is the best way to view HTTP response headers from a request to a specific URL? Telnet or is there some other really good team or tool?

I use the Firefox httpfox extension to view all HTTP requests and responses (including the header and body) initiated from the web browser in the interval I specify (by clicking the record start and stop recording buttons). httpfox presents data in a structured way in which I can quickly find the query I am interested in. It perfectly complements LiveHTTPHeaders because httpfox can also view requests in the past.

I find that Fiddler is my weapon of choice, although there are firefox plugins. Fiddler will show you all the HTTP requests, their response status, all the headers, various views (raw, hex, image), timeline view, HTTPS Connects, that's all.

On Linux, I use:

wget -S [url]

Gets a file and shows all the headers sent by the server.

On Windows, you can use the same command if Cygwin is installed; either on the regular command line if the environment variables were set correctly, or through the Cygwin command window.

  • HttpFox for Firefox is pretty good. It will show headers in real time. I prefer its Live HTTP Headers .
  • Microsoft Fiddler for Internet Explorer is a web-based debugger that logs all HTTP traffic between your computer and the Internet. Fiddler allows you to check all HTTP traffic, set breakpoints, and tinker with incoming or outgoing data.
  • Wireshark is a complete network protocol analyzer. This is good, but it can be redundant if the HTTP headers are all that is required. This has problems if the client and server are on the same machine.

Using a recent version of Firefox (19.0 in my case), go to "Tools" → "Web Developer" → "Web Console" ( Ctrl + Shift + K on Windows), and then refresh the page by creating a query log.

Then, by clicking on one of the first GET requests, the one that has the page URL opens a window with information about this, including request and response headers. It works out of the box, there is no need for additional add-ons.

Check out httpie , a very nice Python tool: enter image description here

You can use the --headers parameter to view only headers:

Firebug addon for Firefox is the easiest way, I think.

For Internet Explorer, Fiddler will work. Or you can use all Wireshark .

There is a better choice (from my point of view)

This Firefox extension refers to HTTPfox. You can see only the title, but much more information. This is a very complete HTTP parser.

If you are familiar with the developer tools in your browser, open the network tab in the developer tools, refresh the page, and click the headers tab. Response headers will be listed. For example, this page sends this header:

 HTTP / 1.1 200 OK
 Cache-control: public, max-age = 60
 Content-Type: text / html;  charset = utf-8
 Content-Encoding: gzip
 Expires: Fri, 01 Mar 2013 02:00:20 GMT
 Last-Modified: Fri, 01 Mar 2013 01:59:20 GMT
 Vary: *
 X-Frame-Options: SAMEORIGIN
 Date: Fri, 01 Mar 2013 01:59:19 GMT
 Content-Length: 13555

Chris Pederick has a great addon / plugin / extension called a Web developer .

It works with Chrome, Firefox and Opera and has powerful dev features, as well as the ability to "View response headers." You can find it on the "Information" tab.

In Internet Explorer, inside the developer tools (press F12), go to the "Network" tab and click "Start Capture." Refresh the page, click "Go to the detailed view" and you will get a very good overview of the request and response data.
