Description

I recently ran into a situation where it would have been useful to have access to header values in the rewrite rules. In particular it would be useful sometimes to API version with a header like this.

    <match pattern="{scheme}://{host}:{port}/api/{path=**}?{**}">
        <rewrite template=""{scheme}://{host}:{port}/api/{$header[version]}/{path}?{**}""/>
    </match>

As implied above the rewrite function plugin model seems like an excellent way to provide basic access to header information.
