My application is using all sorts of libraries, from pear db, quickform to smarty. So it was difficult for me to provide the sample code.
Now I have just created a simple upload file (please copy and paste from below). Which does nothing but logs the access to find out about double post.
I had tried many different php versions and all produced same problem. Let me know what you find out. If you'll upload a small text file you'll see that there are two entries in log file for one access.
The platform to test is IIS (ISAPI) php 5 and Internet explorer 6. (IE 7 may not post values twice but it will display some page not found error.)
<?php
set_time_limit ( 300);
if (@$_POST['submitted'] == 'yes')
{
$csv_file = $_FILES['csv_file'];
if ($csv_file['size'] > 0)
{
$fp = fopen('access.txt', 'a');
fwrite($fp, 'Accessed at '. date('d-m-y H:i:s u'). "\r\n");
fclose($fp);
header('Location:http://www.google.com');
exit;
}
else if ($csv_file['error'] == UPLOAD_ERR_FORM_SIZE || $csv_file['error'] == UPLOAD_ERR_INI_SIZE)
{
$error = "File size exceeds max allowed size of whatever";
}
else
{
$error = "There was error in uploading your file.";
}
}
?>
<html>
<head>
<title>
test
</title>
</head>
<body>
<?php
if (isset($error))
{
echo "<B>$error</B>";
}
?>
<form method="post" enctype="multipart/form-data">
<input type="file" name="csv_file" />
<input type="hidden" name="submitted" value="yes" />
<input type="submit" value="Submit" />
</form>
</body>
</html>

Are you sure it's not something in your code?
I am also using IE/IIS/PHP and I have a form that on submission closes the page and opens up a new window displaying "Your data has been saved" and it does not create 2 rows in my MSSQL database.
