Sometimes when you have a web application deployed to your local host it is more convenient to get the data for it from a remote host. Add the following to the end of your apache2\conf\httpd.conf to redirect all requests for the localhost/ws endpoint to a remote one (will require an Apache restart).
# Pull data from another host instead of localhost. SSLProxyEngine On ProxyPass /ws https://remote.host/ws ProxyPassReverse /ws https://remote.host/ws
Note: SSLProxyEngine allows this to work with HTTPS URLs.
If you want to exclude a request from being redirected to the remote host, and instead to get data from your local machine add the following:
ProxyPass /ws/myservice/person !
If you are using Tomcat or JBoss with jk_mod you may also need to add the following to allow the resource to be serviced locally:
JkUnMount /ws/myservice/person ajp13
