The *protocol* does not, but the HTTP/1.1 specification does. However, it should be noted that *all* modern browsers accept relative URI's vs. the requirement of absolute URI's. Thus, the header is "non-standard," but is not "wrong." Your point is accurate, though: it should include the full resource. > erm .... <META> should be in a html document inside the <HEAD>, not > *anywhere*. That's the recommended order, but it's not required. Not even in 1982 when the spec was written. In fact, the placement in HEAD is so that, with the original specifications, a server would be permitted (though again, not required) to read the META tags within HEAD to form and send its own headers via HTTP in conjunction with the plain-text data from the document. > Very, very, very bad idea.

Once again, for anyone who hasn't been paying attention or who doesn't yet have the acquired knowledge from their own painful experiences, *never* copy and paste code from this list or any other medium. Always evaluate it yourself first. This list is meant for assistance and those on it provide "pseudocode," not production-worthy code. The rest is, as has always been, at your own risk. -- </Daniel P.
