I posted this query back in December:
http://forum.nginx.org/read.php?2,233497
And the issue was fixed shortly afterwards in the 1.3.x branch.
I'm now seeing the same issue again (static items coming from proxy cache + SPDY not displaying).
However this time, the log does not show 499 error anymore.. it just shows successful 304. However, looking at firefox web console, the first few static items come back as 304 without problems, then the next set of static items come back with no response at all.. (no response header, no body).
The setup looks like this:
Firefox -> Nginx 1.3.15 -> HAproxy -> Tomcat
Has this bug crept back in, or is this a new one? Also reproduced on 1.3.13.
Can't seem to reproduce the issue if I take out HAproxy in the middle though.
