Apache mod_proxy

[Amin Taheri]

I have this in the httpd.conf file, but should it even be enabled at all? Does anyone know of a plesk service that depends on mod_proxy?

<Proxy *>
Order Deny,Allow
Deny from all
</Proxy>

I know that tomcat runs on port 8080 as a "proxy" according to nmap, but am not sure if these two things are connected.

$nmap -sS -O localhost

8080/tcp open  http-proxy

$nmap -sV -O localhost

8080/tcp open  http        Apache Tomcat/Coyote JSP engine 1.1

Does anyone know for sure?

As a follow up, plesk (or the vendors httpd) apaprently loads several mod proxy modules as default.

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so

Does anyone know of any good reason to have these enabled - basically do any plesk services depend on these modules?

In a typical Plesk environment where you have one Web/Application server doing everything, mod_proxy will probably never be used.

I don't know of any "click here to enable mod_proxy_ftp" features in Plesk (or any other proxy-based features), so I wouldn't see it used commonly.

Personally, the only time I've ever used mod_proxy are in complex firewalled environments where I have machines in different DMZ's and only permitting traffic on certain ports using mod_proxy to funnel the traffic.

The other being in a Apache 2.2 environment with mod_proxy_ajp to talk to Tomcat instead of having to use mod_ajp.

The only exception would be to your thought process. Since I don't have any Plesk servers that have a Tomcat license, and actual java applications deployed into the container, I couldn't tell you if they use the HTTP connector by simply doing 8080 proxy's or if they use mod_ajp to do this.
