In NIO, there doesn't seem to be a simple way to set a custom HttpRequestFactory
--------------------------------------------------------------------------------
Key: HTTPCORE-132
URL: https://issues.apache.org/jira/browse/HTTPCORE-132
Project: HttpComponents Core
Issue Type: Wish
Components: HttpCore NIO
Affects Versions: 4.0-alpha6
Environment: Java 5. Dev platform is OS X Leopard but I doubt that's
relevant.
Reporter: Rachel Greenham
Priority: Minor
It appears that for developing a server application using NIO, you can't easily
define a replacement HttpRequestFactory. It's hardcoded to create a new
DefaultHttpRequestFactory in DefaultServerIOEventDispatch, in a method that
can't be overridden because the subclass method also references a *private*
data member (the allocator) of DefaultServerIOEventDispatch. It could be done
by also instantiating and supplying an external ByteBufferAllocator in the
overridden method, which "wastes" the instance created in the constructor. (I
notice the constructor that lets you supply an allocator in 4.0-alpha6 is gone
from later versions - but I'm not even interested in replacing the allocator, I
just want to replace the request factory.)
The way I am doing it is by actually *copying* the current source of
DefaultServerIOEventDispatch to my project (with a rename) to make my own
modified version to implement IOEventDispatch - which seems excessive for the
small change I actually want. The change I made was simply to have a
constructor that allows me to supply an already-instantiated
HttpRequestFactory, in a similar fashion to the constructor of
BufferingHttpServiceHandler takes an instantiated HttpResponseFactory.
This also stops this IOEventDispatch from creating a new instance of the
*factory* for each hit, which it seems to be doing at the moment...
