Dear all,

System: Win2k
PHP: 5.0.0b4
Curl: libcurl/7.10.8 OpenSSL/0.9.7c

Having great trouble using PHP5/Curl to pull requests through SOCKS proxy.
 Requests pulled through HTTP proxy work fine. The error returned consistantly
is "Empty reply from server". I am running a local proxy service 'spoonproxy',
 on a Win2k dev machine.

A failed request (SOCKS proxy over port 1080) looks something like this
(with a print_r of the $ch curl handle).

- --------------------------------
START EXAMPLE: FAILED REQUEST

* About to connect() to localhost:1080
* Connected to server (127.0.0.1) port 1080
> GET http://localhost/ HTTP/1.1
[...]
* Empty reply from server
* Connection #0 left intact
Error number: 52

A successful attempt looks something like this (HTTP proxy over port
8080 - everything exactly the same, just using port 8080 instead of 1080).

* About to connect() to localhost:8080

The code I am using for this demo is:

<?php
$ch = curl_init ();
curl_setopt ($ch, CURLOPT_URL, "http://localhost/");
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt ($ch, CURLOPT_PROXY, "localhost:1080");
$result = curl_exec($ch);
echo "Error number: ".curl_errno($ch)."\n";
echo "Error message: ".curl_error($ch)."\n";
echo "Result: ".strlen($result)." bytes\n";
echo $result;
print_r(curl_getinfo($ch));
?>

Where the CURLOPT_PROXY is being toggled between 1080 (SOCKS) and 8080
(HTTP).

Any ideas on what I am doing wrong?

Thanks!

Andy
