Sudheer Vinukonda created TS-3173:
-------------------------------------
Summary: Configuration to control list of protocols advertised in
the NPN/ALPN list
Key: TS-3173
URL: https://issues.apache.org/jira/browse/TS-3173
Project: Traffic Server
Issue Type: Improvement
Components: HTTP, HTTP/2, SPDY
Reporter: Sudheer Vinukonda
Currently, proxy.config.http.server_ports allows to configure supported/allowed
list of protocols for a given proxy port. The same list gets sent as the
advertised protocol list in the NPN/ALPN advertisement.
However, there are situations, where the servers may want the allowed/supported
protocol list to be different to the npn advertised list. For example, you may
want to allow http/1.0 for clients not supporting npn extensions, but, do not
want to advertise http/1.0 in the npn list to prevent clients that support npn
extension from picking http/1.0.
As such, I am wondering if we should have a separate control on the npn/alpn
advertised protocol list.
If so, please provide comments/suggestions. One straightforward choice is to
extend the supported parameters for proxy ports (i.e add another parameter
similar to ":proto"), but, it seems like the configuration becomes more and
more complex and harder to understand/comprehend.
