Tomcat, Comet and Apache

[Sebastiaan van Erk <se...@sebster.com>]

Hi all,

I wrote a Comet servlet for Tomcat, and am ready to deploy it. However, 
my "normal" mode of deployment, namely Apache + mod_jk in front of 
Tomcat no longer works in this situation because Comet requires the NIO 
or APR connectors, which do not support mod_jk. I also tried using 
mod_proxy to proxy requests to the Comet servlet, however mod_proxy 
buffers, which breaks Comet.

I was wondering if there is a good solution to this problem.

I'm ok with using Tomcat as the main server, but then I'm wondering does 
Tomcat have the equivalent of a mod_proxy so that I can service legacy 
pages (php, etc) from Apache?

My preferred solution however would leave Apache as the main server 
since the sheer number of useful modules for apache (rewrite, etc.) 
makes it very nice to have it in front of Tomcat.

Any tips or ideas are welcome!

Thanks,
Sebastiaan van Erk

Hi,

Thanks for the reply.

Turns out that in apache 2.2 there is a flushpackets option in 
mod_proxy. I'll have to upgrade since it's not available in 2.0. I 
missed it because it's not an actual directive but an option to the 
ProxyPass directive (I was looking at ProxyIOBufferSize).

Sebastiaan

my only guess would be to turn off buffering in mod_proxy, if that is 
possible
