Comment:

 In php5.2 the Last-Modified header always blank !!!

 A response with a blank Last-Modified header will be set to "Thu, 01 Jan
 1970 00:00:00 GMT" in some server. The browser will be always send a If-
 Modified-Since header "Thu, 01 Jan 1970 00:00:00 GMT". and the server
 response a 304 status code. Make the browser can not refresh cache.

 sorry my bad english...
