Thanks for the reply Sriram.
I looked at the reference and modified my profile as below.
wdisp/system_0 = SID=PAD, MSHOST=parthoerp, MSPORT=8101, SRCSRV=*:8120, SRCURL=/sap/bc/sap/index.html
The result is, the connection to the backend server is green in the web admin console.
But I am able to access the application only by using the url,
http://<webdisp>:<webdispport>/sap/bc/sap/index.html
which I do not want to expose to the customers. Instead, I wanted the customers to see something like http(s)://shop.xxxx.com/index.html.
I am assuming this http(s)://shop.xxx.com/index.html should be mapped by the firewall team with a DNS to http://<webdisp>:<webdispport>/sap/bc/sap/index.html.
Is that right? Or, is there any other way we can achieve this within the web dispatcher like using url rewrite / filter rules etc.? I was reading this and not sure what is the right way.
Thanks..
