Restrict Iview URL visibility in browser

Dear Experts,

I have a requirement of restricting the URL's that gets displayed on opening any Iview in a new window where the whole path of the object gets displayed in the browser to just http://<server>:<port>/irj/portal.

for example:

From:

http://<server>:<portal>/irj/servlet/prt/portal/prtroot/com.sap.portal.navigation.contentarea.default?NavigationTarget=navurl://fabd516f241d4ab0fa442f7e5b1574bd&HistoryMode=2&TarTitle=Portal

To:

http://<server>:<port>/irj/portal

Kindly guide.

Thank you in advance,

Regards,

Disha.
