Change default URL for CRM_UI

Hello,

After refresh ,CRM_UI transaction from our CRM 7 ABAP system takes to old URL

We want to change the host in the URL to new one

I found this link How to change URL of CRM_UI_START

But wanted to check how should I make an entry in table HTTPURLLOC,currently it has no entries within it

Or is there some other way to make the change to default URL used by CRM_UI tcode ?

Kindly please help
