If web page load causes redirect to another page, keeps reloading redirected page instead of URL in settings

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use an URL setting that sometimes will not be available (for example, server 
is suspended temporarily for backup). Choose to reload the page occasionally.
2. Wait for URL to be unavailable and then redirected.
3. Once redirected to different URL, screen saver will keep reloading this 
"new" URL, even after the URL in the setting returns to availability.

What is the expected output? What do you see instead?
I expect the "set" URL to always be displayed if it is available. Instead, once 
things go off the rails and a redirected URL shows up, it stays up.

What version of the product are you using? On what operating system?
v 2.5, on Lion (10.7.4).
