Redirect to HTTP behind load balancer (apart from localhost) with URL rewrite

Just a short "note to self for future" post as found a few variations for part of this online but needed to pull them together.

Requirement is:

• Ensure all HTTP requests are redirected to HTTPS
• Handle the fact that the web server is behind a load balancer that terminates HTTPS
• Allow for local HTTP requests via a custom port

<rewrite> <rules> <rule name="Redirect to https" enabled="true" stopProcessing="true"> <match url="^(.*)$" /> <conditions> <add input="{HTTP_X_FORWARDED_PROTO}" pattern="https" negate="true" /> <add input="{HTTP_HOST}" pattern="localhost" negate="true" /> </conditions> <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" /> </rule> </rules> </rewrite>
