AJP protocol is configured ProxyPass using the mod_proxy_ajp
|ProxyPass /app ajp://backend.example.com:8009/app|
may be you mean using a directly the http protocol for proxying the backend
|ProxyPass /app http://backend.example.com:8080/app|
ajp, is more convenient because simplify the things and make transparent
the proxying process to tomcat connector, i.e. the info about the SSL
connection between the frontend and client.
Here there is some doc:
https://tomcat.apache.org/connectors-doc/common_howto/proxy.html
http protocol, can be also repleace ajp, but you need to make some
"plumbing" with HTTP headers and tomcat connectors

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

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).

https. If not, are there plans to incorporate this ability into TDS?
