How to configure mod_proxy to ProxyPass based on http vs https?

Question

I have Apache Tomcat running with SSL enabled. I have Apache HTTP Server acting as a reverse proxy so my if users hit http://myserver/tomcat/ they are passed to http://myserver:8080.

ProxyPass /tomcat/ http://myserver:8080/
ProxyPassReverse /tomcat/ http://myserver:8080/

I have Apache HTTP server configured for SSL as well so when users hit https://myserver/tomcat/ they should be passed to https://myserver:8443/.

With the current ProxyPass & ProxyPassReverse configuration they are going to be redirected to the non-ssl URL. How can I setup the proxy pass so that it redirects to different protocol and port based on the incoming request?

That is, if someone comes in via HTTPS how can I redirect them to my tomcat @ https://myserver:8443?

Update:

@mike-insch

I tried:

NameVirtualHost *:443

<VirtualHost *:80>
    ProxyPass /tomcat/ http://myserver:8080/
    ProxyPassReverse /tomcat/ http://myserver:8080/
</VirtualHost>

<VirtualHost *:443>
    ProxyPass /tomcat/ https://myserver:8443/
    ProxyPassReverse /tomcat/ https://myserver:8443/
</VirtualHost>

Now when I visit: https://myserver/tomcat/ I get "page not found". In the error log I see "File does not exist: /var/apache2/htdocs/tomcat"

Which is correct, but I expected the request to be routed to tomcat running at https://myserver:8443/.

Guess I need to look more at the virtual hosts, unless something looks glaringly wrong.

Answer 1

You need to do this via two independent <VirtualHost *:X> directives. Your HTTP directives go inside <VirtualHost *:80> while your HTTPS directives go inside <VirtualHost *:443>. Adjust as required if your server has multiple Address Based or Name Based virtual hosts configured. See the Apache 2 documentation for full details.
