In Strategy Web, objects have a 'Share' option available in the right-click menu to get the URL which can be used to share it with the other users. The base URL which contains the Web server name as shown below, cannot be modified out-of-the-box.

This technical note describes the steps to customize the URL.
This is occurring because Strategy Web is behind a reverse proxy.
<root MSTR web directory>\WEB-INF\
<parameter name="configServletPath" value="http://<web server>:port/Strategy.../"/>
