Scenario 2: Browser - AS-ABAP Communication Through a Reverse Proxy

This graphic is explained in the accompanying text

The browser communicates always with the AS-ABAP through a reverse proxy server. For this reason all generated URLs must contain the name and port of the reverse proxy server.

Example

Example:

Proxy: www.sap.com (http:80, https:443)

Host: webas.sap.corp (http:1080, https:1443)

HTTPURLLOC

MANDT	SORT_KEY	PROTOCOL	APPL	HOST	PORT
100	010	HTTP	*	WWW.SAP.COM	80
100	011	HTTPS	*	WWW.SAP.COM	443

As there is no application filter, table http synchronizes all requests in order to generate new URLs. The protocol is the factor that decides which entry is used.
