asp.net mvc获取绝对URL（在代理之后）

Question

user --> internet --> server1 (iis proxy) --> server2 (hosting the website)

I'm trying to get the absolute url.

The code below has worked without any problem when we were not using a proxy:

string fullUrl = Url.Action("Bar", "Foo", new RouteValueDictionary(new { id = pid, search = search }), Request.Url.Scheme);
string fullUrlEncoded = HttpUtility.UrlEncode(fullUrl);

However now instead I receive this absolute url with internal ip:

 http://192.168.0.3/Foo/Bar/5 

How can this be solved?

Answer 1

I ended up by hardcoding the url in the appsettings and adding it to the url as suggested by Chris Pratt. I could not use any X-Forwarded-For header, it was enabled but I didn't receive that information, so could not use it.
