Provide a clean mechanism to attatch user define attributes to connections
--------------------------------------------------------------------------
Key: HTTPCLIENT-915
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-915
Project: HttpComponents HttpClient
Issue Type: New Feature
Components: HttpConn
Reporter: dave irving
Priority: Minor
It would be nice to have a way to attach user defined attributes to a
connection.
Ideally it'd be nice if such support could be added to HttpClientConnection,
but understandably this may not be possible due to back-compatibility issues.
So, we could have something like HttpConnectionContext perhaps (or similar)
with:
HttpConnectionContext#setAttribute(String name, Object value)
Object HttpConnectionContext#getAttribute(String name)
This would be made available in the HttpContext of a request (like the
connection is today):
HttpConnectionContext connectionContext = (HttpConnectionContext)
httpContext.getAttribute(ExecutionContext.HTTP_CONNECTION_CONTEXT);
This would make a few things much cleaner to implement than they are today: The
most obvious being my current use case of wanting connection isolated cookies.
Currently to achieve this goal we need to provide custom client connection +
connection operator + connection manager implementations. Then there is no
clean way to currently obtain the actual connection instance created by a
custom operator in the HttpContext: As it's wrapped by the connection pool and
#getWrappedConnection is protected - so we need to resort to reflection in
interceptors.
Providing a clean mechanism for attaching user defined attributes to a
connection instance as described above would make such implementations far far
simpler.
