Microsoft : IIS Redirect

1. Redirect HTTP to HTTP
 

        <rewrite>
            <rules>
                <rule name="redirect" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions>
                        <add input="{HTTPS}" pattern="^OFF$" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" />
                </rule>
            </rules>
        </rewrite>

• Permanent (301) – preferable type in this case, which tells clients that the content of the site is permanently moved to the HTTPS version. Good for SEO, as it brings all the traffic to your HTTPS website making a positive effect on its ranking in search engines.
• Found (302) – should be used only if you moved the content of certain pages to a new place *temporarily*. This way the SEO traffic goes in favour of the previous content’s location. This option is generally not recommended for a HTTP/HTTPS redirect.
• See Other (303) – specific redirect type for GET requests. Not recommended for HTTP/HTTPS.
• Temporary (307) – HTTP/1.1 successor of 302 redirect type. Not recommended for HTTP/HTTPS.
