Subject: What are the rules for caching?
|> The proxy caches a doc when all of the following hold:
|> * method is GET
|> * request is not a query (no '?' in the URL)
|> * not protected (no "Authorization" header)
|> * the received number of bytes matches the "Content-length" header
|> * response contains a "Last-modified" and/or "Expires" header
|> (dynamic script responses don't => shouldn't be cached)
|Does this apply the other way around too: Dynamic script responses
|*shouldn't* have a "Last-modified" and/or "Expires" header?
what about if the script will always return the same page - ie. like a
gateway to another WWW object storage system ?
and what about "Pragma: no-cache" ?
