Pre-Authenticated URLs with IIS URL Rewriting

readme.md

This configuration allows having pre-authenticated URLs.

-- i.e. mapping /auth/xyz/some/resource to /some/resource?token=xyz

NOTE: This DOES preserve other querystrings on the URL.

pre-authenticated urls were useful for our elasticsearch reverse proxy to allow us use authentication with sense.

web.config

<system.webServer>
  <rewrite>
      <rules>
        <rule name="pre-authenticated-urls" stopProcessing="true">
          <match url="auth\/([^\/]+)(.*)" />
          <action type="Rewrite" url="{R:2}?token={R:1}" appendQueryString="true" logRewrittenUrl="true" />
        </rule>
      </rules>
    </rewrite>
</system.webServer>
