RESOURCE MAPPING DURING UNIVERSAL RESOURCE LOCATOR CHANGES IN DISTRIBUTED COMPUTING SYSTEMS

Abstract:

Technologies are disclosed for resource mapping during URL changes in multi-tenant distributed computing systems. The distributed computing system may resolve a URL by using a tenant and/or site name extracted from the URL to retrieve an entry in a site map table. The entry includes an address to a database that contains the requested content. After a tenant or site name has been changed, or if the tenant or site have been moved, the distributed computing system will resolve pre-existing URLs to the old entry, resulting in a file not found error. In some embodiments, during an operation that changes a tenant or site name, a redirect URL containing the new tenant and/or site name is added to the old entry. When a request addressed to a URL containing the old tenant and/or site names is received, the distributed system sends a redirect response that includes the redirect URL.
