I have a web application hosted on multiple servers some of which are on https. How can I check from code behind if a page is currently in http or https?

You can refer to the Request.IsSecureConnection property on the HttpRequest class. For a full reference outside a page, user control or alike, use HttpContext.Current.Request.IsSecureConnection.

Beware- IsSecureConnection can give false negatives. http://stackoverflow.com/questions/998397/why-does-request-issecureconnection-return-false-when-true-is-expected – Jude Allred Mar 28 '11 at 21:13

Answer is little old, so now, for me it was a bit changed with owin. I got the value by "System.Web.HttpContext.Current.GetOwinContext().Request.IsSecure". May be this comes handy for some one later. :) – MGR May 11 '16 at 11:11

Page.Request.Url.Scheme

works as well. It returns http, https, etc.

Update for Aspnet Core 2.0, now, you should use Request.IsHttps inside your controllers.

As of NET Core 2.2 you can use ```Request.Scheme``` which should return either ```https``` or ```http```. Either work fine on Windows servers although on Ubuntu ```IsHttps``` and ```Request.Scheme``` both say the request is not secure for me so not sure if this is a bug or something configured wrongly. – Robin Wilson Jan 04 '19 at 23:54

Alternatively:

Request.ServerVariables["SERVER_PROTOCOL"];

This returns `HTTP/1.1` for me on both http and https while `Request.IsSecureConnection` returns as expected. – atheaos Jan 27 '16 at 15:27

In .net core I use:

Context.Request.Scheme == Uri.UriSchemeHttps

Try this,

aCookie.Secure = HttpContext.Current.Request.IsSecureConnection
