Last-Modified HTTP header and JavaScript databases

Domino R5.0a does not send Last-Modified headers for responses from databases that have the database option "Web access: Use JavaScript in generating pages" selected. In Domino R5.0.1 this is still the behavior for requests which specify the HTTP/1.0 protocol. However, if a request specifies HTTP/1.1, Domino 5.0.1 will return a Last-Modified header along with the header "Cache-Control: private", which indicates that the response may be cached by a browser's local cache, but not by public caches (for example, proxy server caches).
