Actually, that's not correct (I just tested this by printing a page as 
the result of a POST in NN3.01, NN4.0, and MSIE3.0). I can also do a 
"Reload" in NN and it reposts the data just fine; however, doing a 
"Refresh" in MSIE doesn't work. I would speculate that there might be 
something like the "Expires" or "Pragma" header that is being sent back 
by the CGI script that tells the browser not to cache the document and 
that this is why it can't be printed. I've never used "Expire" or 
"Pragma" headers, so it is just a guess.

Another, and more serious, drawback is that the query length of a GET 
is limited to (I think) 256 characters while the query length of a POST 
is (theoretically) unlimited.
