+ * <p>Typically Customizers perform tasks such as: <ul>
+ * <li>process header fields that may be injected by a proxy or load balancer.
+ * <li>setup attributes that may come from the connection/connector such as SSL Session IDs
+ * <li>Allow a request to be marked as secure or authenticated if those have been offloaded
+ * and communicated by header, cookie or other out-of-band mechanism
+ * <li>Set request attributes/fields that are determined by the connector on which the
+ * request was received
