Apache :: WSDL Resolving To End Point - Loadbalancer IP

We are hosting a webservice application behind a Loadbalancer and the webservice is accessed via a ReverseProxy.However when we try to access the WSDL we see the endpoint loadbalancer IP coming in the response instead of the reverse proxy url.

The httpd.conf has the below entries -

ProxyPass /abc http://IP1:Port1/abc
ProxyPassReverse /abc http://IP1:Port1/abc

Our application [URL] ....

So when we hit the above url to access the WSDL it give us the WSDL return

<wsdl:service name="abc">
<wsdl:port binding="impl:abc" name="abc">
<wsdlsoap:address location="http://IP1:Port1/abc"/>
</wsdl:port>
</wsdl:service>

This exposes our backend IP address and Port. The desired return is

<wsdl:service name="abc">
<wsdl:port binding="impl:abc" name="abc">
<wsdlsoap:addresslocation="http://abconline.com/abc"/>
</wsdl:port>
</wsdl:service>
