Re: new HTTP_Header package?

me again ... searching for votes :-) Wolfram Kriesing wrote:

i needed to handle http-caching properly, so i started a package, which (one day) shall handle any http-header operations, such as caching, etc. there is one base-class HTTP_Header which implements common header methods and the first class, that i needed is the HTTP_Header_Cache, which wraps http-caching, see example below i could imagine other http-handlings to be implemented in HTTP_Header_* classes to make http-header handling a bit easier source is here http://os.visionp.de/tmp/HTTP_Header/Header.php.txt http://os.visionp.de/tmp/HTTP_Header/Cache.php.txt what do you think? example use of HTTP_Header_Cache

    $httpCache = new HTTP_Header_Cache();

    // we have a css-file here
    $httpCache->setHeader( 'Content-Type' , 'text/css' );

    // if the file is cached in the user-agent
    // and the template was not compiled again, we exit here
    $httpCache->exitIfCached( !$tpl->compiled() );

    // otherwise we send all the headers
    $httpCache->sendHeaders();

    ... and keep on working the script

implemented by hand, without class:

    header('Pragma: cache');
    header('Cache-Control: public');

    if( !$tpl->compiled() && $_SERVER['HTTP_IF_MODIFIED_SINCE'] )
    {
        header('HTTP/1.1 304 Not Modified');
        exit;
    }

    header('Content-Type: text/css');
    // the header has to loo like this:
    // Last-Modified: Mon, 27 Nov 2000 00:00:00 GMT
    header('Last-Modified: '.date('D, d M Y H:i:s T') );
