The cheesy way to do this with virtually no effort would be to enable
the "p" trace flag and rebuilding in debug mode. In other words, given:
> #if 0
>     HTSetTraceMessageMask("sop");
> #endif
change the zero to a one.

I say cheesy because the file produced is hardcoded to "w3chttp.out" (in
HTTP.c, around lines 1190-1230 or so), and it's contents are replaced
with every request. If you need or want more control over the output
file, or you don't want a debug build, have a look at the HTFWrite class
- it looks like it gives you more control over storing request output.
