But JSF doesn't return the If-Modified-Since header either. It's a
request-header. Please help me understand your comment in light of this
fact.
[1] 14.25 If-Modified-Since
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
The If-Modified-Since request-header field is used with a method to
make it conditional: if the requested variant has not been modified
since the time specified in this field, an entity will not be returned
from the server; instead, a 304 (not modified) response will be
returned without any message-body.
