Question

I receive HTTP PUT requests on a server and I would like to redirect / forward these requests to an other server.

I handle the PUT request on both server with PHP.

The PUT request is using basic HTTP authentication.

Here is an example :

www.myserver.com/service/put/myfile.xml

redirect to

www.myotherserver.com/service/put/myfile.xml

How can I do this without saving the file on my first server and resending a PUT request using CURL?

Thanks!

HTTP/1.1 defines status code 307 for such redirect. However, PUT is normally used by client software and you can pretty much assume no one honors 307.

The most efficient way to do this is to setup a proxy on Apache to redirect the request to the new URL.

This is how you can proxy it in PHP,

$data = file_get_contents('php://input');
$mem  = fopen('php://memory'); 
fwrite($mem, $data); 
rewind($mem);   
$ch = curl_init($new_url);                             
curl_setopt($ch, CURLOPT_PUT, true);  
curl_setopt($ch, CURLOPT_INFILE, $mem); 
curl_setopt($ch, CURLOPT_INFILESIZE, strlen($data)); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    
curl_exec($ch);       
curl_close($ch);  
fclose($meme);
