i don't think there ready-made solution that, shouldn't hard implement (wcf) service , database @ server side - if client can deal redirections. when need create link page (say, http://a.b.com/c/d), you'd create random link in service (http://your.service.com/path/redirectingservice.svc/getlink/abcdef), store in database new row following information: original link (a.b.com/c/d), expiration date (now.adddays(1)), random link (abcdef).

you can return link service (http://your.service.com/path/redirectingservice.svc/getlink/abcdef) client.

in service implementation, you'd random link value parameter, query database entry link. if link has expired, return error (e.g., 404, 500, etc.) client. if link valid, can return 307 location header set actual link.
