Question

However, this browser should not only display the image, it should also, in a small window above the image, display the HTTP response line and all HTTP headers received from the server serving the HTTP request. For instance, an HTTP request for http://classes.bus.oregonstate.edu/ba371/reitsma/images/cob.png, results in the following response line and headers being returned by COB's Web server:

In addition, we want to distinguish the HTTP response status from the headers and display it in a separate Status code textbox (see example above).

Simple HTTP Image Browser Browser Image URL: http// Hlasses bus. oregonstate.edu/ba371/reitsma/mages/cob png Status Code: 200: OK Headers:Connection:close Go Accept-Ranges: bytes Content-Length: 59587 Content-Type: image/png Date: Mon, 19 Mar 2018 23:32:04 GMT ETag: "a7b8794edb 63d31:0" Last-Modified: Wed, 22 Nov 2017 21:46:08 GMT
