Symbiostock - Technical Support / Changes at Paypal that Affect IPN
« on: September 06, 2013, 14:45 »
I just received this e-mail from Paypal:
"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 sites 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.
My question is: Do we need to do anything for our Symbiostcok sites? Will this change impact our symbiostock Paypal IPN?
Thanks in advance for any feedback.
