Hi John,
Is AJP having any advantage particularly over ProxyPass?
Thanks,
Guan

I agree, an Apache front end is a simple and standard thing to do.
AFAIU, the user still is using SSL encryption, its just that Apache is doing
that instead of Tomcat. So it would be good for any of us to make some
measurements comparing large binary data transfers.

Hi Steve
I was hoping that would work. That any proxying, whether AJP or other, would
be hidden. I have had problems in the past getting AJP proxying to work, if I
need to do that. Can you send me (offline) the part of you httpd.conf where
you proxy over to tomcat using AJP?
We have had good success using Apache & AJP. Apache as a front end provides a
number of options, particularly WRT authentication and this might provide for a
compromise should HTTPS be too much of a bottle neck. I have not tested the
impact of HTTPS compared to HTTP (it would be easy enough to do using simple
file transfers).
