How to install apache modules

/usr/local/apache/modules  missing so many modules how can i install them ?

After 2 days of research i found my solution

there is no way to install modules, need to re compile

down below code for mod_proxy module to use proxy for domains (i used for railo cos i wanted some domain run 8888 port)

/usr/local/apache/bin/apxs -a -i -c /tmp/apache-build/httpd-2.2.27/modules/proxy/mod_proxy.c /tmp/apache-build/httpd-2.2.27/modules/proxy/proxy_util.c
