Redirect from HTTP to HTTPS

You can redirect from HTTP to HTTP request in ASP.NET website using the web.config in ASP.NET web sites.

Open web.config file in the root directory of your website and add the following <rewrite> section in the <system.webServer> section.

Example: Redirect from HTTP to HTTPS in web.config

<rewrite>
    <rules>
        <rule name="HttpToHttps" stopProcessing="true">
            <match url=".*" ignoreCase="true" />
            <conditions>
                <add input="{HTTPS}" pattern="^OFF$" />
            </conditions>
                <action type="Redirect" redirectType="Permanent" url="https://www.mywebsite.com/{`{R:0}`}" />
        </rule>
    </rules>
</rewrite>

You can remove redirection if you are running it in your development machine localhost by adding one more condition, as shown below.

Example: Ignore localhost

<rewrite>
    <rules>
        <rule name="HttpToHttps" stopProcessing="true">
            <match url=".*" ignoreCase="true" />
            <conditions>
                <add input="{HTTP_HOST}" pattern="localhost" negate="true"/>
                <add input="{HTTPS}" pattern="^OFF$"/>
            </conditions>
                <action type="Redirect" redirectType="Permanent" url="https://www.mywebsite.com/{`{R:0}`}" />
        </rule>
