HTTP Configuration.

This class is a holder of HTTP configuration for use by the HttpChannel class. Typically a HTTPConfiguration instance is instantiated and passed to a ConnectionFactory that can create HTTP channels (e.g. HTTP, AJP or FCGI).


The configuration held by this class is not for the wire protocol,
but for the interpretation and handling of HTTP requests that could
be transported by a variety of protocols.

An interface that allows a request object to be customized
for a particular HTTP connector configuration.  Unlike Filters, customizer are
applied before the request is submitted for processing and can be specific to the
connector on which the request was received.


Typically Customizers perform tasks such as:


    

  • process header fields that may be injected by a proxy or load balancer.

  • setup attributes that may come from the connection/connector such as SSL Session IDs

  • 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

  • Set request attributes/fields that are determined by the connector on which the
request was received
