I want to modify third party longpoll module nginx_http_push_module (
http://pushmodule.slact.net/ ) to notify upstream every time a request
hangs
waiting for a new publication, sending original headers and all, so I
know
in my upstream application that there is a user connected on the
channel,
and even what user is it, if I can have access to the session cookies.
The
results of this notification request isn’t really going anywhere and is
not
of interest.
My idea was to generate a new request to a “internal” marked location,
copying the relevant headers from the original request, while handling
the
later (thus inserting a new request in the nginx HTTP request processing
stack, and discarding its results). This new request would be
independent
from there on.
At first it seemed a simple approach, but now that I browsed through
some
examples modules, I am not so sure anymore. I failed to find any module
that
does something like this, and I could not find the relevant API to
“offspring” such relatively independent HTTP request.
Do you think this is a good approach? Can you point me the API I should
use,
or a sample module that does something like this?
