How to update URL in Address Bar after Web Dispatcher Redirect?

In our current set-up, have a website that is accessible externally, where requests go to a SAP Web Dispatcher 7.49 connected to a SAP NW Gateway 7.5 system. icm_mod_redirect has been configured to rewrite certain URLs to External Aliases onn the Gateway System.

The observed behaviour is as follows:

1. User goes to external facing website e.g.

2. Request hits SAP Web Dispatcher, which has a rule in icm_mod_redirect to rewrite to /home in the back-end Gateway Server (which is an External Alias for the Fiori Launchpad)

3. The browser loads the Fiori Launchpad Logon Page and the user enters their username/password (URL in the address bar is still

4. The Fiori Launchpad loads and the URL in the address bar changes to

Is there any setting we can change so that in step 3, when the Fiori Launchpad Logon Page is loaded, the URL in the address bar updates to From a technical perspective, I understand that the rewrite already happens on the back end. We are just looking from a user-experience perspective because it seems like the rewrite is being obscured in the background before login. I suspect this is a technical limitation of the Web Dispatcher or it's how HTTP is implemented as a standard, but wanted to confirm. Thanks!

    So want to redirect at webdispatcher level? If YES please use filter_rules (Parameter:icm/HTTP/mod_0)

    Let me know if you need more help.

      Hi Yogesh,

      Thanks for your reply. Upon further reading, I was able to expand my understanding of the issue and resolve it.

      In the filter rules file, I had put originally down the HTTP Action RegIRewriteURL to change from to There is also the HTTP Action RegIRedirectURL which can be used. Based on the blog below, I found that Redirect would change the URL directly in the browser bar, unlike Rewrite.

      By changing from RegIRewriteURL to RegIRedirectURL, we were able to create the desired behaviour in the browser.
