Does Meta-refresh require a full url

Question

Does a meta refresh tag require a full url?

I have code that looks like this, which seems to work just fine, but when I load it in lynx text browser, it says this is bad HTML. It seems to suggest that the full URL is required (http://mydomain.com/blah.htm).

Answer 1

If you want this to be relocatable, generate it on-the-fly with JS.

Answer 2

From practice I can say it does not require full url. However it may not be specified in any HTTP version and up to the browser. FF/IE/Chrome all seem to work without a full url.
