Comet Servlet with a reverse proxy in front of it
Is there any way to put a reverse proxy in front of a Comet servlet? I
tried apache but thats a no go because it uses a single thread per
connection, which is not scaleable, then I tried nginx, which perhaps I did
something wrong in my setup but in the client code, the call to
getInputStream never returns, indicating something is wrong. I apologize
for not providing too many details and just proposing a general question,
but Im hoping there is a general solution to this problem. If you guys
needs server specific details I can provide later today when I get home
from work.

Here is my config for using nginx as a reverse proxy in front of tomcat.
Seems to work so far. Just replace the question marks with your
configuration
server {
listen 80;
server_name ??????;
root /var/lib/tomcat7/webapps/?????.
location / {
proxy_http_version 1.1;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://127.0.0.1:8085/;
}

Hey,
I actually got this working so far with nginx(and by so far I mean the
random connection errors I was getting with apache2 have not surfaced yet).
Ill post the nginx config setup later today when I get home for the benefit
of anyone else who wants to do this.

I don't believe so. There is work being done on supporting Websocket
through mod_proxy but it will likely never support Comet.

Only some Apache httpd MPMs are one-thread-per-connection.

I think that httpd + Tomcat is not going to work, here. I'm not sure
about Nginx. If you find something that works, please post back with
your findings.
