no-cache, please!

Ok, a little weird this one.

i have a page that seams to get stuck in the cache,

 

Now i thought adding

header("Cache-Control: no-cache")

would of worked...

 

basically it shows the first bob.jpg, then i change a few things and it stays the same, i then load the file from its true path and the changes where their but not on the one below!

 

<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
//Creates bob.jpg
//kinda long so didn't post
//done creating
$filename = "bob.jpg";
echo "<EMBED src='$filename' width='100%' height='100%' href='$filename'></EMBED>";
?>

 

i hope that makes sence

 

any ideas ?

this works for me - got it from another member  a while back

 

Header("Cache-control: private, no-cache");
Header("Expires: Mon, 26 Jun 1997 05:00:00 GMT");
Header("Pragma: no-cache");

You could try to force the image to be loaded again by faking a different name for it - add a random number to it, i.e. bob.jpg?random#here.  The browser will think it's different and load it again from the server.

weird thing is that also failed,

 

i'll review my code.. and see if i can make a simple example to post.

Are you sure you're trying to load the correct version of the script. I've had instances where I'm debugging a script and whenever I run it, my changes don't appear -- it always turns out to be that I've upload the test script to the wrong area or it's uploaded to the right area, but my browser is pointed to the wrong area.

I've noticed problems with Firefox sometimes when trying to reload pages... where changes I've made don't show up until I clear the cache... even changing the name of files etc...  Not sure how it happens.

Oh yes kenrbnsn, checked for that (done it too many times)

 

Humm i am using firefox i'll play with IE see what happens
