I think it's sad that nobody thinks we could convince Microsoft to 
change the behavior of .Net. As it stands, System.Uri in .Net is 
mangling URLs on the *client* side, apparently to help protect 
*servers* that might still be vulnerable to a flaw like
http://www.microsoft.com/technet/security/bulletin/fq00-019.mspx
which, by the way, turns 10 years old this week.

Anybody from the .Net team at MSFT want to chime in?

ISTM at the very least MSFT should release official patches (even if 
they're hotfixes that must be manually obtained) for .Net 2.0 and 3.5 
(lots of us still run primarily 2.0) to provide something like a 
DoNotSimplifyPath property for a UriBuilder object so that code like 
Andrew's would be able to work reliably.
