I need to observe what my browser is sending to my server under two different circumstances. I am betting that, even when the return content type is application/x-zip-compressed that IE only makes byte-range requests when the URL it is requesting does not have a query string.

I have observed this phenomenologically. I had the following simple webpage: 


<form action=file.zip>
<input type=submit value="Download Now!">

[download]
and IE would resume the download if I cancelled in the middle.

However the following webpage: 


<form action=download.cgi?filename=file.zip>
<input type=submit value="Download Now!">

[download]
did not result in IE making partial requests for the zip file even though the CGI program is returning the same MIME type as above and the file does download successfully. But for some reason, a partial request is not supported here.

I hypothesize that IE is not making a partial request but would like to ensure this by getting a printout of what HTTP is being sent to my webserver.

So my question is

How can I get an exact printout of everything that was in IE's request.

i was nearly successful with HTTPi A small webserver written entirely in Perl, but it only serves executables and HTML files.

I think I have seen various Perl HTTP sniffers around, but I couldn't find any in a websearch just now.
