very strange ... reloading doesn't get current version of page

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Very frustrated by a quirk in a normal html form submission (a search box).

First it was getting no $_POST vars, though I checked the form method,  
and used print_r($_POST) to see. Eventually I realized that when I  
refreshed the browser it would not really refresh.

For example I put in a phpinfo() call just to make sure I was editing  
the right search.php -- I refreshed and got the good old phpinfo. then I  
commented that line out. I refreshed and got the good old phpinfo  
anyway. I deleted the line entirely and still get it.

So it's getting a cached version from somewhere... I can't imagine  
where; I've been building sites on this box for over a year and this is  
the first time I've seen anything like this.
