Ken Giusti created DISPATCH-1788:
------------------------------------
Summary: HTTP1.x adaptor fails to honor HTTP/1.0 connection
semantics
Key: DISPATCH-1788
URL: https://issues.apache.org/jira/browse/DISPATCH-1788
Project: Qpid Dispatch
Issue Type: Bug
Components: Protocol Adaptors
Affects Versions: 1.15.0
Reporter: Ken Giusti
Assignee: Ken Giusti
Fix For: Backlog
The HTTP/1.x codec does not handle HTTP/1.0 connection lifecycle correctly.
There is a race when the HTTP/1.0 server sends a response with a valid
content-length to a router that has queued multiple outstanding request
messages. The adaptor does not wait for the connection to close after the
response is received and begins to send the next pending request as the server
is closing the connection.
>From RFC7230, Persistence:
{quote}A recipient determines whether a connection is persistent or not based
on the most recently received message’s protocol version and Connection header
field (if any):
o If the "close" connection option is present, the connection will not persist
after the current response; else,
o If the received protocol is HTTP/1.1 (or later), the connection will persist
after the current response; else,
o If the received protocol is HTTP/1.0, the "keep-alive" connection option is
present, the recipient is not a proxy, and the recipient wishes to honor the
HTTP/1.0 "keep-alive" mechanism, the connection will persist after the current
response; otherwise,
o The connection will close after the current response. A client MAY send
additional requests on a persistent connection until it sends or receives a
"close" connection option or receives an HTTP/1.0 response without a
"keep-alive" connection option.
