Another (legal although controversial) example is

	HTTP/1.1 200 OK
	Content-Location: overhere.html
	Content-Type: text/html
	Content-Base: http://www.newbase.com/
	...

In fact, I think most parsers now use lazy parsing in order to avoid
wasting cycles on parsing headers that are not used anyway. A sideeffect of
this is that dependencies between header fields are easier to deal with.
