Step 2 of the note 2041742 - UI Theme Designer für ABAP: Correct host for custom theme access
Step 2 says:
The HTTP request that the proxy forwards to the SAP Web Application server must contain the following header fields. The reverse proxy needs to be configured to add the missing information so that the Web Application server can calculate the correct client URL.
Host: <hostname>:<port>
Clientprotocol: <protocol>
x-sap-webdisp-ap: <protocol>=<port>
Where should I add these config ? in SAP Web Dipsatcher ?
if yes, then where exactly in the SAP Web Disp ?
