* specific protocols, and manage them in a uniform way. Once a channel is
* created (via nsIIOService::newChannel), parameters for that request may
* be set by using the channel attributes, or by QI'ing to a subclass of
* nsIChannel for protocol-specific parameters. Then, the URI can be fetched
* by calling nsIChannel::open or nsIChannel::asyncOpen.
*
* After a request has been completed, the channel is still valid for accessing
* protocol-specific results. For example, QI'ing to nsIHttpChannel allows
* response headers to be retrieved for the corresponding http transaction.
