Managing redirects is an important aspect of search engine optimization. In order to maintain page rank for resources within your website, you need an effective strategy to manage URL changes.

As you transition from traditional URLs to optimized URLs, or when you change the configuration of your optimized URLs, it is important to ensure that:

Links throughout your own Web site and to your own external resources can simply be updated to the new URLs. However, external references to your site must be redirected in order to prevent unresolved links.

The URL optimization classes are responsible for transforming URLs into search and navigation queries, and vice-versa. They do not implement redirect logic. In order to redirect incoming requests, you must include the appropriate logic in your application controller. By comparing an inbound URL to the canonical (optimized) form, you can redirect to the canonical URL in cases where the inbound URL is different.

Oracle recommends including HTTP 301 redirects. Unlike HTTP 302 redirects, which collect ranking information and index content on a site against the source URL, 301 redirects apply this information to the destination URL.
