Portlet containers may return header names with PortletRequest#getPropertyNames() [1] and values with PortletRequest#getProperty(String) [2] but are not required to do so. Case in point: Liferay Portal does not return the "If-Modified-Since" header.

So I think this can only be officially tightened up in the servlet case.

[2] http://portals.apache.org/pluto/portlet-2.0-apidocs/javax/portlet/PortletRequest.html#getProperty(java.lang.String)
