Description:
------------
Hi,

    I've been trying to use the SOAP extension to get a WSDL through a proxy, but it seems that the http header sent to the proxy server are invalid. I tried with Squid 2.5.STABLE11 and Privoxy 3.0.3 without success. This is not a duplicate of the bug 29211.

    From what I see, the request sent to the proxy server is pure HTTP/1.1, with the server specified in the "Host:" header and the command being "GET /dir/xxx.wsdl HTTP/1.0".

    From the HTTP RFC, in HTTP/1.0 you can only use :

GET http://www.example.com/dir/xxx.wsdl HTTP/1.0

    With HTTP 1.1 you can use the method above or :

GET /dir/xxx.wsdl HTTP/1.1
Host: www.example.com

    Since very few (if any) proxy server fully support the HTTP/1.1 method, I suggest we stick with the good old HTTP/1.0 GET.

Reproduce code:
---------------
<?php
	$client = new SoapClient("http://service.mappoint.net/standard-30/mappoint.wsdl", array("proxy_host" => "192.168.0.18", "proxy_port" => 8118, "trace" => 1));

print_r($client->__getFunctions());
?>

Expected result:
----------------
To get the WSDL.

Actual result:

Here's a dump of the packets sent to the proxy :

0000   00 04 00 01 00 06 00 07 e9 ad 37 45 00 00 08 00  ..........7E....

0060   64 6c 20 48 54 54 50 2f 31 2e 30 0d 0a           dl HTTP/1.0..

There's also this part that follow in another packet (the "Host:" header :

0000   00 04 00 01 00 06 00 07 e9 ad 37 45 00 00 08 00  ..........7E....
0010   45 00 00 52 39 85 40 00 40 06 7f 73 c0 a8 00 4b  E..R9.@.@..s...K

0060   0d 0a                                            ..

Then the answer from the proxy (privoxy 3 in this case) :
