Tool to view response headers [closed]

Answer 1

If you are familiar with the developer tools in your browser, open the network tab on the developer tools, refresh the page, then click on the headers tab. The response headers will be listed. For instance 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

Answer 3

I find that Fiddler is my weapon of choice, although there are firefox plugins as well. Fiddler will show you all the HTTP Requests, their response status, all the headers, with different views (raw, hex, image), a timeline view, HTTPS Connects, everything.

Answer 4

Using a recent version of Firefox (19.0 in my case), going to menu Tools -> Web Developer -> Web Console (Ctrl + Shift + K on Windows) then refreshing the page produces a log of requests.

Then clicking on one of the first GET requests, the one with the URL of the page, opens a box with information about it, including request and response headers. It works out of the box, no need for fancy-shmancy add-ons any more.

Answer 5

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

Answer 6

I use the httpfox Firefox extension to view all HTTP requests and responses (including header and body) initiated from the web browser in the interval I specify (by pressing the start-recording and the stop-recording buttons). httpfox presents the data in a structured way in which I can quickly find the request I am interested in. It nicely complements LiveHTTPHeaders, because httpfox can view requests in the past as well.
