/**
* State Transition Flags
*
* These flags indicate the various states that requests may transition
* through as they are being loaded. These flags are mutually exclusive.
*
* For any given request, onStateChange is called once with the STATE_START
* flag, zero or more times with the STATE_TRANSFERRING flag or once with the
* STATE_REDIRECTING flag, and then finally once with the STATE_STOP flag.
* NOTE: For document requests, a second STATE_STOP is generated (see the
* description of STATE_IS_WINDOW for more details).
*
* STATE_START
* This flag indicates the start of a request. This flag is set when a
* request is initiated. The request is complete when onStateChange is
* called for the same request with the STATE_STOP flag set.
*
* STATE_REDIRECTING
* This flag indicates that a request is being redirected. The request
* passed to onStateChange is the request that is being redirected. When a
* redirect occurs, a new request is generated automatically to process the
* new request. Expect a corresponding STATE_START event for the new
* request, and a STATE_STOP for the redirected request.
*
* STATE_TRANSFERRING
* This flag indicates that data for a request is being transferred to an
* end consumer. This flag indicates that the request has been targeted,
* and that the user may start seeing content corresponding to the request.
*
* STATE_NEGOTIATING
* This flag is not used.
*
* STATE_STOP
* This flag indicates the completion of a request. The aStatus parameter
* to onStateChange indicates the final status of the request.

/**
* State Type Flags
*
* These flags further describe the entity for which the state transition is
* occuring. These flags are NOT mutually exclusive (i.e., an onStateChange
* event may indicate some combination of these flags).
*
* STATE_IS_REQUEST
* This flag indicates that the state transition is for a request, which
* includes but is not limited to document requests. (See below for a
* description of document requests.) Other types of requests, such as
* requests for inline content (e.g., images and stylesheets) are
* considered normal requests.
*
* STATE_IS_DOCUMENT
* This flag indicates that the state transition is for a document request.
* This flag is set in addition to STATE_IS_REQUEST. A document request
* supports the nsIChannel interface and its loadFlags attribute includes
* the nsIChannel::LOAD_DOCUMENT_URI flag.
*
* A document request does not complete until all requests associated with
* the loading of its corresponding document have completed. This includes
* other document requests (e.g., corresponding to HTML <iframe> elements).
* The document corresponding to a document request is available via the
* DOMWindow attribute of onStateChange's aWebProgress parameter.
*
* STATE_IS_NETWORK
* This flag indicates that the state transition corresponds to the start
* or stop of activity in the indicated nsIWebProgress instance. This flag
* is accompanied by either STATE_START or STATE_STOP, and it may be
* combined with other State Type Flags.
*
* Unlike STATE_IS_WINDOW, this flag is only set when activity within the
* nsIWebProgress instance being observed starts or stops. If activity
* only occurs in a child nsIWebProgress instance, then this flag will be
* set to indicate the start and stop of that activity.
*
* For example, in the case of navigation within a single frame of a HTML
* frameset, a nsIWebProgressListener instance attached to the
* nsIWebProgress of the frameset window will receive onStateChange calls
* with the STATE_IS_NETWORK flag set to indicate the start and stop of
* said navigation. In other words, an observer of an outer window can
* determine when activity, that may be constrained to a child window or
* set of child windows, starts and stops.
*
* STATE_IS_WINDOW
* This flag indicates that the state transition corresponds to the start
* or stop of activity in the indicated nsIWebProgress instance. This flag
* is accompanied by either STATE_START or STATE_STOP, and it may be
* combined with other State Type Flags.
*
* This flag is similar to STATE_IS_DOCUMENT. However, when a document
* request completes, two onStateChange calls with STATE_STOP are
* generated. The document request is passed as aRequest to both calls.
* The first has STATE_IS_REQUEST and STATE_IS_DOCUMENT set, and the second
* has the STATE_IS_WINDOW flag set (and possibly the STATE_IS_NETWORK flag
* set as well -- see above for a description of when the STATE_IS_NETWORK
* flag may be set). This second STATE_STOP event may be useful as a way
* to partition the work that occurs when a document request completes.
*
* STATE_IS_REDIRECTED_DOCUMENT
* Same as STATE_IS_DOCUMENT, but sent only after a redirect has occured.
* Introduced in order not to confuse existing code with extra state change
* events. See |nsDocLoader::OnStartRequest| for more info.
