This tutorial will show you how to configure your website in IIS 10 so that all incoming http:// links to the site will be redirected to their secure https:// versions.

Because IT-Security IS important
It is assumed that a server has already been set up with Microsoft Windows Server 2016 and the current IIS 10, so that the web page in question can be accessed on both http and https.
– How to install IIS 10 on Windows Server 2016 (German only)– How to get a free SSL-certificate from Let’s Encrypt for IIS Websites (German only)
Preparing your server
Before we can start configuring you server, another tool needs to be installed: URL Rewrite. It is an official extension to IIS and has been installed together with Server Manager up to version 9. From version 10 onwards, URL rewrite must be installed manually. Microsoft’s free EXE should be downloaded, which can be found here: LINK
Building a server configuration
However, the rule is still deactivated. To activate it, find the menu item Enable Rule and click on it.
Finished! Http requests are now forwarded automatically to https. Best practice is to test it immediately by opening the website in any browser.
Summary
With little effort, the entire websites traffic is encrypted. Other services, such as WebDAV, can be encrypted with the same certificate too. Have a look at this tutorial to see how it is done: Encrypt WebDAV with Let’s Encrypt (German only).
Setting up an HTTP/HTTPS redirect in IIS
Once the SSL certificate is installed, your site still remains accessible via a regular insecure HTTP connection. To connect securely, visitors must specify the https:// prefix manually when entering your site address in their browsers.
In order to force a secure connection on your website, it is necessary to set up a certain HTTP/HTTPS redirection rule. This way, anyone who enters your site using a link like «yourdomain.com» will be redirected to «https://yourdomain.com» or «https://www.yourdomain.com» (depending on your choice) making the traffic encrypted between the server and the client side.
Below are steps to setup a IIS HTTPS redirect:
- Download and install the URL Rewrite module.
- Open the IIS Manager console and select the website you would like to apply the redirection to in the left-side menu:
- Double-click on the URL Rewrite icon.
- Click Add Rule(s) in the right-side menu.
- Select Blank Rule in the Inbound section, then press OK.
- Enter any rule name you wish.
- In the Match URL section:
- In the Conditions section, select Match all under the Logical Grouping drop-down menu and press Add.
- In the prompted window:
- Un-check the Append query string box.
- Select the Redirection Type of your choice. The whole Action section should look like this:
- Click on Apply on the right side of the Actions menu.
The IIS redirect can be checked by accessing your site via http:// specified in the URL. To make sure that your browser displays not the cached version of your site, you can use anonymous mode of the browser.
The rule is created in IIS, but the site is still not redirected to https://
Normally, the redirection rule gets written into the web.config file located in the document root directory of your website. If the redirection does not work for some reason, make sure that web.config exists and check if it contains the appropriate rule.
- In the sites list of IIS, right-click on your site. Choose the Explore option:
- Explore will open the document root directory of the site. Check if the web.config file is there.
- If the web.config file is missing, you can create a new .txt file, put the aforementioned code there, save and then rename the file to web.config.

- Remove the HTTP binding from your site (leave HTTPS in place)
- Add another site
- Make sure that the new site has HTTP binding
- Configure HTTP Redirect as shown:
Now all HTTP request will redirect to your HTTPS site and will preserve the rest of the URL.

Once set up, the redirect would always end at this url:
Real site (HTTPS binding only, actually contains code and virtual directories)
Application pool’s Advanced Settings: Enable 32-Bit Applications : False
Http_Redirect site (HTTP binding only, is a blank shell of a folder with no directories)
Application pool’s Advanced Settings: Enable 32-Bit Applications : True
EDIT: Another detail, tied to query string preservation:
Per suggestion in this post (http://www.developerfusion.com/code/4678/permanent-301-redirect-with-querystring-in-iis/)
Add $S$Q at the end of the domain and make sure the box for Redirect all requests to exact destination is checked. Then it will save the query string as well.

I found a workaround:
Consider what in IIS is consired a website: simply a set of rules, the path in which get files and its bindings.
Furthermore, there’s available a function called «HTTP Redirect» (included standardly in IIS), that redirect an host to another, keeping all subdirectory (it makes a relative path). The workaround is to leave just the binding for HTTPS (port 443) in your website, and create another with the binding on HTTP (port 80) and set for this an HTTP redirect to your URL with https://.

You can add the URL Rewrite module to IIS (IIS 7 or higher) which allows you to add create the redirect in a visual way. The module can be downloaded here.
This step-by-step tutorial worked wonders for me and explains that when using this module, all it actually does is add some code to your web.config file as such:

I have found that the
syntax will only work for the website’s ROOT web.config file.
If the rewrite rule is applied to a virtual web.config file, then use..

You can try this code with web.config file. If your URL is http://www.example.com then it will be redirect to this URL https://www.example.com.

You could use the RequireHttpsAttribute for simple cases.
«Represents an attribute that forces an unsecured HTTP request to be
re-sent over HTTPS.»
I’m not sure you’d want to use this to enforce HTTPS across a large site though. Lots of decorating to do, and opportunity to miss controllers.

This answer is not exactly for OP but for those who could not make it work like me and have come across this (and although I know there is 403 not 404 error in OP), please refer to this answer if you are getting 404 instead: https://stackoverflow.com/a/6962829/5416602
Please check that you have binding for HTTP port (80) and not only HTTPS port (443) in your IIS

I’m unable to add comments, but thought this supplementary info would maybe help somebody.
I implemented the Global.asax idea with the 301 Permanent Redirect, and added http binding to the site in IIS. It still gave me 403 Forbidden until I remembered to untick «Require SSL» in SSL Settings.

I have changed and tried some of the IIS options but with no luck.
How can i do this?
I’m using IIS 7.5 and ASP.NET 2.0
asked Jun 16, 2011 at 9:33
The approach described in this blog article works well.
Summary:
1) Turn on «Require SSL» setting for the site.
2) In the Error settings configuration for 403 errors set it to «respond with 302 redirect» with the new URL set to the full URL with the https:// prefix.

Just in case someone else runs into a http:// site that will not redirect. You also have to have the port 80 binding added to the site.
