X-Header Insertion
Extension header (X-header) fields are fields that are added to protocol headers for specific purposes such as user identification, device detection, etc. The X-header mechanism allows additional entity-header fields to be defined without changing the protocol. However, these fields are assumed to be unrecognizable by the recipients.
X-header insertion inserts X-headers in HTTP or WSP GET and POST Request packets and HTTP Response packets. You can configure rules to insert X-headers in HTTP or WSP Request and HTTP Response packets. The charging-action associated with the rules contain the list of X-headers to be inserted in the packets.
