I think you need to drop the "~/" and replace it with just "/", I believe / is the root
STOP RIGHT THERE! :-) unless you want to hardcode your web app so that it can only be installed at the root of a web site.
"~/" is the correct thing to use, but the reason that your original code didn't work as expected is that ResolveUrl
(which is used internally by Redirect
) tries to first work out if the path you are passing it is an absolute URL (e.g. "**http://server/**foo/bar.htm" as opposed to "foo/bar.htm") - but unfortunately it does this by simply looking for a colon character ':' in the URL you give it. But in this case it finds a colon in the URL you give in the ReturnPath
query string value, which fools it - therefore your '~/' doesn't get resolved.
The fix is that you should be URL-encoding the ReturnPath
value which escapes the problematic ':' along with any other special characters.
Response.Redirect("~/Login.aspx?ReturnPath=" + Server.UrlEncode(Request.Url.ToString()));
Additionally, I recommend that you (or anyone) never use Uri.ToString
- because it gives a human-readable, more "friendly" version of the URL - not a necessarily correct one (it unescapes things). Instead use Uri.AbsoluteUri - like so:
Response.Redirect("~/Login.aspx?ReturnPath=" + Server.UrlEncode(Request.Url.AbsoluteUri));
