I've received an email from PayPal saying they will no longer support HTTP: 1.0 protocol and scripts need to be updated to reflect this. I've included the entire email below. Does this effect users of joom donation?
Here's the email:
In a bulletin dated October 18, 2011, we announced that we were going to expand the number of IP addresses for
www.paypal.com
to improve our site’s performance, scalability and availability. As part of this transition, we planned to discontinue support for HTTP 1.0 protocol starting October 7, 2013.
We have recently identified that this change may impact the ability of some of our merchants to perform IPN (Instant Payment Notification) post-back validation or PDT (Payment Data Transfer) posts to
www.paypal.com
and ipnpb.paypal.com. This happens when the IPN or PDT scripts use HTTP 1.0 protocol and do not include the “Host:
www.paypal.com”
or “Host: ipnpb.paypal.com” header in the HTTP request.
Additional Details
Starting October 7, 2013, we will require all incoming requests to have a “Host” header which complies with HTTP 1.1 Specifications. This header was not required under HTTP 1.0. IPN and PDT scripts using HTTP 1.0 may start failing with “HTTP/1.0 400 Bad Request” errors after October 7, 2013, which will result in IPN messages not being validated successfully, or PDT scripts not being able to retrieve transaction information.
Action Required before October 7, 2013
Merchants need to update their IPN and/or PDT scripts to use HTTP 1.1, and include the “Host” and “Connection: close” HTTP header in the IPN postback script.
Example with Host as
www.paypal.com
(please make necessary changes if you are using ipnpb.paypal.com):
ASP
//Set values for the request back
req.Method="POST";
req.Host="'
www.paypal.com
'";
req.ContentType="application/x-www-form-urlencoded";
Perl
$req=HTTP::Request->new('POST', '
www.paypal.com/cgi-bin/webscr
');
$req->content_type('application/x-www-form-urlencoded');
$req->header(Host=> '
www.paypal.com
');
$req->header(Connection=> 'close');
PHP
// post back to PayPal system to validate
$header="POST /cgi-bin/webscr HTTP/1.1\r\n";
$header .="Content-Type: application/x-www-form-urlencoded\r\n";
$header .="Host: www.paypal.com\r\n";
$header .="Connection: close\r\n\r\n";
Java
HttpsURLConnection uc=(HttpsURLConnection) u.openConnection();
uc.setDoOutput(true);
uc.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
uc.setRequestProperty("Host", "
www.paypal.com
");
uc.setRequestProperty("Connection", "Close");
The PayPal Sandbox has been configured to reject any HTTP requests without the “Host” header with HTTP 400 error. Merchants can use the Sandbox environment to certify the changes to their IPN and PDT scripts.
