FW: EPP Command Question

["Hollenbeck, Scott" <shollenbeck@verisign.com>]

FYI.  I received the private message included below back in August, and I
intend to address the comment in the next version of the EPP specifications.
I'm sending the suggestion to the list so it gets properly archived.

The genesis of the suggested text involved a request to add clarifying text
so that implementers understood that they may have to deal with commands and
responses that don't get exchanged in a tidy one-for-one fashion.

For the EPP spec:

"Be sure you consider the mechanics of command-response 
synchronization if you implement an EPP client that supports 
asynchronous command-response exchanges.  If you implement an
EPP server, you must support asynchronous command-response 
exchanges unless you can guarantee synchronous-only clients."


For the TCP spec (append to Section 3):

"An EPP client may support asynchronous command-response
exchanges.  In this case, a server may receive, in the 
course of a single read operation, data that includes
multiple client commands or command fragments.  The server 
must scan the incoming client data, extract and execute 
properly formed commands as described above, and carry over 
any remaining data as a prefix to the data received in the
next read operation.


I'll keep my day job...:-)
