Re: 304 Not Modified header not working within a class

Hi list, my first message here :) To the point: I'm programming a class that takes several CSS files, parses, compresses and saves into a cache file. However, I would like to go a step further and also use the browser cache, handling the 304 and 200 header types myself. Now, what is the problem? If I do it within a function, there is absolutely no problem, everything works like a charm. However, when I implement that same concept into my class, there is no way I can send a 304 Not Modified header, when the data is *over* ~100 bytes. Hi Camilo

For what it is worth I have implemented cacheing in a class and for me the 304 not modified header gets sent fine ... some example headers output is below together with the relevant code snippet.. // See if client sent a page modified header to see if we can // just send a not modified header instead if (isset($_SERVER['HTTP_IF_MODIFIED_SINCE']) && $_SERVER['HTTP_IF_MODIFIED_SINCE'] == self::$_gmmodtime) { header('HTTP/1.1 304 Not Modified'); return null; } if (isset($_SERVER['HTTP_IF_NONE_MATCH']) && stripslashes($_SERVER['HTTP_IF_NONE_MATCH']) == self::$_etag) { header('HTTP/1.1 304 Not Modified'); return null; } HTTP/1.x 304 Not Modified Date: Wed, 20 Jan 2010 07:21:32 GMT Server: Apache/2.2.11 (Ubuntu) Connection: Keep-Alive Keep-Alive: timeout=5, max=1000 Etag: 444fbd9951f540ec1b6928db864c10dc Expires: Sun, 24 Jan 2010 06:16:06 GMT Cache-Control: public, must-revalidate Vary: Accept-Encoding I hope it helps..
