I have a question about transport mechanisms
between cardholder and merchant.
In SET External Interface Guide it is stated
that:
---------------------------------------------------------------------------------------
"Meanwhile, since there is no standardized channel for passing data upstream from helper applications through browsers, the upstream problem will have to be handled in a platform/browser dependent fashion. Methods may include operating system supported inter-process communication, manually driven file-based interaction, or browser-dependent client APIs." --------------------------------------------------------------------------------------- What is the most common methodology used at this
time, to pass the DER-Encoded Message from a Client Browser to the merchant side
web server application stated in the previous MIME message SET-SET-URL field
?
(ie. the SET-SET-URL: http://www.merchant.com/cgi-bin/doset.exe) According to mentioned guide DER Encoded Message (say PReq) follows the http structure: --------------------------------------------------------------------------------------- POST uri HTTP/1.0 Content-Type: application/set-payment Content-Length: xxx [PReq goes
here...]
--------------------------------------------------------------------------------------- What is the standard mechanism to post the PReq to
an application at the merchant server via the customer�s web browser? Since it
is an interoperability issue, in order to interact any browser or a Wallet or a
helper application in the Internet communicating with any merchant, I think
there should be a common known way to acomplish message exchange which we don't
know. Could somebody make it clear posting the DER encoded data (not the
Initiation message, since the Initiation messages are carried with MIME bodies.)
from any Cardholder helper application to the merchant side which two of the
entities (CH and Merchant)have no common way of transporting the
Data?
Any helper document or comment of a sample mechanism will be appreciated. Gokhan AFACAN
