Your question isn't very clear.
Changing the HTTP Host header has no impact on the URL displayed in the browser - it just reflects the address of the page currently being displayed.
Changing the host header in HTTP_REQUEST may change the content delivered by the pool member, if the pool member is serving multiple sites distinguished by Host name.
However, if the pool member returns a redirect, it may redirect to the host specified in the Host header, which will change the address in the browser bar:
browser requests http://bob.com/tobee
pool_A member responds with a 200 OK
- browser bar displays bob.com/tobee
browser requests http://bob.com/nottobee
pool_B member responds with a 302 Redirect to http://www.bob.com/nottobee/
- browser bar now displays www.bob.com/nottobee/
Use the Browser developer tools Network tab to determine if multiple requests are being made for each of these cases.
