Some will. For example, the Federal Reserve Bank of New York has such
restrictions. I suggest you take your existing home page and put links to
two 1x1 gifs where one of the gifs is at port 80 and one at 8080 for a few
days. Then look at your logs and compare the number of IP addresses that
download each gif. You might even look at the RDNS names and see if a
pattern emerges.
