We released nghttp2 v1.13.0.
This release fixes several build issues, and add a new library feature. nghttpx session affinity feature has been improved.
We can now cancel non-DATA frame transmission from
nghttp2_before_frame_send_callback by returning
from there. This could be useful for some cases where we know the
transmission of a frame should be avoided. The upcoming use case is
cache digest. After queuing PUSH_PROMISE frame, but before actually
sending the frame, we may know client has the fresh copy of the
resources by CACHE_DIGEST frame. In that case, it is desirable to
cancel transmission of PUSH_PROMISE frame.
nghttp2_on_frame_not_send_callback is invoked if frame transmission
is canceled as usual.
We fixed number of warnings with Sphinx 1.4.0.
nghttpx’s session affinity using client IP is improved by using the similar hashing technique described in https://github.com/RJ/ketama
