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

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.

This graphic is explained in the accompanying text.

Example Example

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

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

End of the example.

HTTPURLLOC
CLIENT	SORT_KEY	PROTOCOL	APPL	HOST	PORT
`100`	`010`	`HTTP`	`*`	`http://WWW.SAP.COM`	`80`
`100`	`011`	`HTTPS`	`*`	`http://WWW.SAP.COM`	`443`

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