The things:
* I have a nginx handmade compiled under the hood
* I have an official zope+plone installation on native windows
* I have a django based application inside the cygwin
* I have a tomcat+cas installation on native windows

All of that seem to be configured correctly.

What i want to do is to make my nginx a reverse proxy of the 3 others appli=
cations.

Because of some other application needs (wsgi served with flup/socket) i ne=
ed
that nginx to live inside the cygwin installation. That's not my concern
afterall :).

The nginx works well for static contents and as the the django  and tomcat
installations reverse proxy.

Here come problems with zope+plone.

If i hit my http://url/plone (nginx mapped point to the plone install as ht=
tp
reverse proxy), the first request (get /) pass, but the other stall as 206
partial content and are very long to be satisfied. The browser seems to be
blocked on some read() call.

I tried a bunch of things nginx side (use epoll, use select, tweak proxy
parameters, stop proxy buffering, set timeouts, set retrys and so on) but i=
 have
not found the right configuration if it is there.

But where it is very strange is that if i make an ssh tunnel from localhost=
:80
to prod_machine:localhost:80, then make some entry into my /etc/hosts to fa=
ke
the dns name. Then browse to http://myurl/plone, no problem, i have the con=
tent,
and all http request are satisfied (js & co.).

I really don't know how to debug that, can it be because the request enter =
from
cygwin, go out to windows re enter cygwin and go for the client?

The fact that throught the ssh tunnel, when i hit the nginx server on my pl=
one
install (like "as normal", i dont hit plone but nginx) work perfectly lives=
 me
without words. Other strange thing is that the CAS application, also http
reverse proxified work like a charm.

Other thing is that if i use the windows nginx binary from nginx website, w=
ith
equal configuration, it works. The only thing is nginx running out of cygwin
stack and compiled for win32.

If someone has some suggestions ....
