Yes, I know. But sometimes (in particular, in my case) remote host doesn't support HEAD requests. GET responses with Last-Modified header and large body. Body is being cached on local host.
Is the "If-Modified-Since" header supported maybe? Or "If-None-Match"
with an Etag instead of a last modified date?
