Misses error code when not 200
by jb (johnwarde@hotmail.com) on 29 Jul 2003 1:12am GMT

the get() method misses the status code when a HTTP code other than 200 is returned. i.e. when a "HTTP/1.1 400 Bad Request" is returned status becomes "Bad" when. I believe it should be 400.

Little code to help with this

Hello,

You can make a session not to expire by using this code.

Its a mixture of PHP and JavaScript and can be used on the same page were your code goes or invoked by a ilayer/iframe from your page. Here is the code.

//First of all we prevent browsers from caching the image

header("Cache-Control: no-store, no-cache, must-revalidate");

header("Cache-Control: post-check=0, pre-check=0", false);

header("Pragma: no-cache");

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");

//This piece of code returns a blank gif

if($_GET[img] > 0){

header('Content-Type: image/gif');

header("Content-Disposition: inline; filename=".time().".gif");

echo base64_decode("R0lGODlhAQABAPcAAAAAAAAAQAAAgAAA/wAgAAAgQAAggAAg/wBAAABAQABAgABA/wBgAABgQABggABg/wCAAACAQACAgACA/wCgAACgQACggACg/wDAAADAQADAgADA/wD/AAD/QAD/gAD//yAAACAAQCAAgCAA/yAgACAgQCAggCAg/yBAACBAQCBAgCBA/yBgACBgQCBggCBg/yCAACCAQCCAgCCA/yCgACCgQCCggCCg/yDAACDAQCDAgCDA/yD/ACD/QCD/gCD//0AAAEAAQEAAgEAA/0AgAEAgQEAggEAg/0BAAEBAQEBAgEBA/0BgAEBgQEBggEBg/0CAAECAQECAgECA/0CgAECgQECggECg/0DAAEDAQEDAgEDA/0D/AED/QED/gED//2AAAGAAQGAAgGAA/2AgAGAgQGAggGAg/2BAAGBAQGBAgGBA/2BgAGBgQGBggGBg/2CAAGCAQGCAgGCA/2CgAGCgQGCggGCg/2DAAGDAQGDAgGDA/2D/AGD/QGD/gGD//4AAAIAAQIAAgIAA/4AgAIAgQIAggIAg/4BAAIBAQIBAgIBA/4BgAIBgQIBggIBg/4CAAICAQICAgICA/4CgAICgQICggICg/4DAAIDAQIDAgIDA/4D/AID/QID/gID//6AAAKAAQKAAgKAA/6AgAKAgQKAggKAg/6BAAKBAQKBAgKBA/6BgAKBgQKBggKBg/6CAAKCAQKCAgKCA/6CgAKCgQKCggKCg/6DAAKDAQKDAgKDA/6D/AKD/QKD/gKD//8AAAMAAQMAAgMAA/8AgAMAgQMAggMAg/8BAAMBAQMBAgMBA/8BgAMBgQMBggMBg/8CAAMCAQMCAgMCA/8CgAMCgQMCggMCg/8DAAMDAQMDAgMDA/8D/AMD/QMD/gMD///8AAP8AQP8AgP8A//8gAP8gQP8ggP8g//9AAP9AQP9AgP9A//9gAP9gQP9ggP9g//+AAP+AQP+AgP+A//+gAP+gQP+ggP+g///AAP/AQP/AgP/A////AP//QP//gP///yH5BAEAAP8ALAAAAAABAAEAAAgEAP8FBAA7");
