The URL-based re-addressing feature is applied based on L7 rule matching for HTTP URLs in addition to re-addressing charging action based on L3/L4 rule matching. HTTP request with specific token or complete URL must be redirected to a separate server and must be transparent to the UE.
Flow-based re-addressed connection
Flow-based re-addressed connection is the default behavior of this feature. In this type, after a HTTP connection is setup with Original Server, all subsequent requests will be sent to it until the URL-based re-addressing rule matches. This behavior holds true even for multiple concatenated HTTP requests in one packet.
