Topic: ProxyPass - How to reduce the amount of virtual hosts

[MofaBertram]

Hi!

I'm running an Apache as a reverse proxy for several Tomcat backends. There's no load ballancing. Each name based virtual host serves one Tomcat via ProxyPass/mod_jk. Since I want to setup a new linux machine I realzied that I'm currently running 30 virtual hosts and because I also want to serve https on the new one the amount of virtual hosts doubles.

So I started to look for another setup where I could reduce the ammount of virtual hosts. I looked for a setup where I can serve all backends with 2 virtual hosts only but the decision for the correct backend still must be made on the virtual host servername. One for http and one for https. My first attempt was to try if-conditions on the servernames but ProxyPass directives are not allowed within if-conditions.

Then I looked for other config setups but honestly I did not found one.

Does anyone have a tip?

For HTTP/80 you could use a VirtualHost _default_:80 and pass on the correct host.
For SSL you need a correct name for a valid certificate unless you have a multidomain certificate.

a more complex solution would be to use mod_rewrite.
