Proxy credentials advice needed

My desktop application (C# 2.0) works just fine and makes tons of
requests via WebRequest and WebClient objects. However, users that are
behind Proxy servers are not able to use the app. I'm sure my head is
not right on this issue and i need to seek advice.

First, I dont really understand why I (the programmer) have to worry
about these details - shouldnt this be somewhere below me on the ISO
stack? But that sounds like complaining, so I'll stop right there.

Second, I dont know how I should handle this. Am i required to fetch
credentials from the user and store it locally? Can i get default
credentials from the OS (or IE)? Note: I have tried this using
CredentialCache.DefaultCredentials, but the values are always blank.

Code snippets would be very helpful and appreciated, but I really
would like to get your opinion on how this should be handled -
conceptually. It just doesnt add up (for me) that every application
that makes web requests, needs to handle this for itself... it should
be down in the OS somewhere (IMHO).

Thanks in advance,

George
