Please be aware that this could have unintended consequences, and should be used in very constrained ways. In particular, there are any number of applications, including VPN applications that use port 80. I would recommend that only specified destinations get such treatment, if you apply it at all.

If somebody is ignorant enough to implement IP over HTTP, why should they be accommodated? There are numerous reasons why there are other port numbers to TCP than 80 and other protocol numbers to IP than 6. We could save a lot by eliminating unneccessary headers... Pete
