apache 2.4 AJP proxy not working - apache

Question

I am trying configure my Apache 2.4 to connect to my backend Tomcat 8.0.28. in my Mac OS X El Capitan.
I used NameBased VirtualHost with AJP support. config file apache_serviceproxy.conf located: /Library/Server/Web/Config/Proxy
<VirtualHost 10.0.1.100:80>
ProxyPreserveHost On
ServerName www.storageway.com.au
ServerAlias storageway.com.au
ServerAdmin cidy.long#gmail.com
ProxyPass / ajp://127.0.0.1:8009/StorageWayServer/
ProxyPassReverse / ajp://127.0.0.1:8009/StorageWayServer/
</VirtualHost>
Tomcat app context is: http://localhost:8080/StorageWayServer, access Tomcat from LAN, every thing works fine. But when I tried to request over Internet, apache 2.4 call Tomcat through AJP not working well.
Tomcat received html request () from apache AJP properly but from then, every inclusive css, javascript and image in the html with wrong request url, it is simple double application context name.
And this is my Tomcat access log:

If I request it from LAN by access Tomcat directly, it works fine, log as:

I tried to find some help from google and tried using
RedirectMatch /StorageWayServer http://www.storageway.com.au/
but I never take the extra application context off from the request url.
Any advice or experience welcome.
Have a good week end!

Don't change the context path in the ProxyPass directive. There are many, many ways to shoot yourself in the foot when you do this.
At a guess, the links on your pages are absolute so they include the context path. When the client then requests these, the ProxyPass directive adds the context path again.
You have three choices:
Redploy your application as the ROOT web app and use
ProxyPass / ajp://127.0.0.1:8009/
Access your application with the context path and use
ProxyPass /StorageWayServer/ ajp://127.0.0.1:8009/StorageWayServer/
Spend days / weeks trying to configure mod_sed or similar to edit the responses on the fly to correct the links.
I've seen large organisations spend huge amounts of time and money an option 3 and I really do not recommend it.
