iframe not refreshing in Firefox

[akshay]

Hello.

 

I'm using a php script to upload file. I've used an iframe inserted on the upload page that refreshes every second/3sec. to display percentage uploaded.

 

forget percentage, lets take a simple example.

 

Presently, my iframe displays last two digits of PHP time() function that change constantly. If you see the live example at: http://mintload.com/upload/upload-single.php

The last two digits of time() function are shown and iframe is refreshed every  1 sec.

But, the moment one clicks "Upload" button, the file starts uploading, but iframe no more refreshes & freezes. In IE7 it works fine. Why not in Firefox Latest Ver: 3.6 ?

 

code for iframe:

header("refresh:1; $_SERVER[php_SELF]");
echo substr(time(),-2,2);

 

My point is, just as in IE, my iframe shouldnt freeze refreshing even if a file is being uploaded. Any code/functions?

The problem is taking place in Firefox.

 

Please help. Thank you.
