these are three files below :
submit.html
<html>
<head>
</head>
<body>
<form action="redirect.php" method="POST" >
<input type="text" name="value" value="test" >
<input type="submit" >
</form>
</body>
</html>
redirect.php
<?php
header("HTTP/1.1 303 See Other");
header("Location: post.php");
?>
post.php
<html>
<head>
</head>
<body>
<?php
if(isset($_REQUEST['value'])) {
echo "the value is : <font color=RED >{$_REQUEST['value']}</font>";
}
?>
</body>
</html>
When I submit, it does redirect to 'post.php', but it doesn't show
"test". If I change the submit.html to use the "GET" method ,and append
"?value={$_GET['value']}" to the url int the redirect.php, it works
well. Why the "POST" method doesn't work? I use "apache http server
2.0.58" with "php 5" , "ms IE 6.0" and "firefox 1.5.0".

You lose posted data when you redirect. You would need to re-post the
data along with sending the redirect, which i'm not sure is possible,
never tried it myself.
Why can you simply include the file?
Since you're using apache, you could use mod_rewrite to transparently
rewrite the request, not sure if that would accomplish what you want to
do.

Because redirection uses the GET method.
You should consider either including post.php into redirect.php or
saving the POSTed values into session variables:
redirect.php
<?php
session_start();
$_SESSION = $_POST;
header("HTTP/1.1 303 See Other");
header("Location: post.php");
?>
post.php
<?php
session_start();
if(isset($_SESSION['value'])) {
echo "the value is : <font color=RED >{$_SESSION['value']}</font>";
}
?>

Yes, it's possible :)
Using Curl, you might try something like this (adjust to fit your
needs):
if( condition )
{
$rePosts = '';
foreach( $_POST as $pk => $pv )
{
$rePosts .= "&$pk=" . urlencode($pv);
}
$rsrc = curl_init( 'http://site_to_redirect_to/remote_script.php' );
if( is_resource($rsrc) )
{
curl_setopt( $rsrc, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt( $rsrc, CURLOPT_POST, 1 );
curl_setopt( $rsrc, CURLOPT_POSTFIELDS, ltrim($rePosts, '&') );
curl_setopt( $rsrc, CURLOPT_HEADER, 0 );
curl_setopt( $rsrc, CURLOPT_FOLLOWLOCATION, 1 );
curl_setopt( $rsrc, CURLOPT_RETURNTRANSFER, 1 );
curl_exec( $rsrc );
curl_close( $rsrc );
exit;
}
else
{
// some error handling...
}
}
hih,

In fact ,the destination that I want to redirect to is not developed by
me , and they won't change their code for me. They use "POST" to get
values ,I have to redirect the POST request.

As others have said - you can't redirect post values. They're sent as part of
the request for the page, and a redirect doesn't resend them.
Your only real choices are to use CURL or send the header information yourself.
Then pass the results back to the client.

You can't. HTTP does not work this way.
