Type a URL into the "URL" edit box and press Enter or click on the "Get" button.
One or more of the edit boxes below the bevel (which are read-only) will be filled in automatically with information arising out of your request.
The contents of the "Sent header" box are fairly constant, with only the pathname and host varying. For example, if you entered the URL http://publish.uwo.ca/~craven/, the sent header would be
GET /~craven/ HTTP/1.0 Host: publish.uwo.ca Accept: www/source, text/html, video/mpeg, image/jpeg, image/x-tiff Accept: image/x-rgb, image/x-xbm, image/gif, */*, application/postscript Content-type: application/x-www-form-urlencoded
The "Events" box shows a log of some of the events that take place in the HTTP interaction. The first part of each line shows the time in seconds after the initial request. A simple example is
0.0: Host resolved 0.0: Connecting to 184.108.40.206 0.0: Packet 1 received, 2852 bytes 0.0: Disconnected
If the file is successfully downloaded, the "Header" box should show the HTTP header lines; for example,
HTTP/1.1 200 OK Server: Sun-ONE-Web-Server/6.1 Date: Fri, 13 Apr 2007 19:07:01 GMT Content-length: 2852 Content-type: text/html Last-modified: Thu, 12 Apr 2007 19:03:22 GMT Accept-ranges: bytes Connection: closeIf the page delivered appears to be "headerless", a warning message will pop up, and the "Header" box will be empty.
Finally, the "Body" box should show the file contents (the whole contents of an HTML file, not just the body element). HTML files from Unix or Linux servers may display with little black rectangles instead of line breaks. Contrast the HTTP header, where each line always has to end with both a carriage return and a line feed and so displays correctly in Windows. Contents of graphics files and other files containing non-printing characters will usually not show properly; for example, for a GIF file, all you see might be GIF89aß.
The "User-Agent" box can be used to specify a particular user agent in the request header. This will cause some servers to respond differently.
