Rewrite URL

  • Alt

APPLIES TO: All API Management tiers

The rewrite-uri policy converts a request URL from its public form to the form expected by the web service, as shown in the following example.

  • Public URL - http://api.example.com/storenumber/ordernumber

  • Request URL - http://api.example.com/v2/US/hardware/storenumber&ordernumber?City&State

This policy can be used when a human and/or browser-friendly URL should be transformed into the URL format expected by the web service. This policy only needs to be applied when exposing an alternative URL format, such as clean URLs, RESTful URLs, user-friendly URLs or SEO-friendly URLs that are purely structural URLs that don't contain a query string and instead contain only the path of the resource (after the scheme and the authority). This is often done for aesthetic, usability, or search engine optimization (SEO) purposes.

Note

Set the policy's elements and child elements in the order provided in the policy statement. Learn more about how to set or edit API Management policies.

    </inbound>
    <outbound>
        <base />
