I have configured apache2 web server on my lan server and now I am configuring virtual host. My objective is to replace the local IP-address in place apache host IP in url.

For example :

I have installed apache web server on 172.30.17.102, when I call url http://172.30.17.102/Proxy1/paramater/list , than it should be go to http://1.224.0.30:8080/dashboard/paramater/list.
I tried below configuration in virtual host setting...

ProxyPass /Proxy1/^ http://1.224.0.30:8080/dashboard/$
ProxyPassReverse /Proxy1/^ http://1.224.0.30:8080/dashboard/$

I am new to apache web server. Please help me to find what I am doing wrong?
