Setting HttpContext.Current.Request.Url.Host
asp.net
Solution
Use the `UriBuilder` class to change URIs, e.g.
var original = HttpContext.Current.Request.Url;
var changed = (new UriBuilder(original) { Host = "newDomain" }).Uri;
URIs are tricky little beasts with plenty of semantics you might not know or expect, so don't go using string functions on them unless you absolutely have to.
Problem
I need to replace the host part of the Uri `HttpContext.Current.Request.Url.Host = "newDomain";` you can't set host. Is there a quick and easy way to do this to a Uri for reusing it to redirect somewhere else?
