-// This file contains classes that are used to cache the contents of a top-level
-// http request (not for sub frames) while that request is parsed for the
-// presence of a meta tag indicating that the page should be rendered in CF.
-
-// Here are a few scenarios we handle and how the classes come to play.
-
-//
-// Scenario 1: Non CF url navigation through address bar (www.msn.com)
-// - Bho::BeforeNavigate - top level url = www.msn.com
-// - MSHTML -> MonikerPatch::BindToStorage.
-//   (IEFrame starts this by calling mshtml!*SuperNavigate*)
-//    - check if the url is a top level url
-//    - iff the url is a top level url, we switch in our own callback object
-//      and hook it up to the bind context (BSCBStorageBind)
-//    - otherwise just call the original
-// - BSCBStorageBind::OnDataAvailable - sniffs data and determines that the
-//   renderer is not chrome. Goes into pass through mode.
-// -  The page loads in mshtml.
-//
-
-//
-// Scenario 2: CF navigation through address bar URL
-// - Bho::BeforeNavigate - top level url = http://wave.google.com/
-// - MSHTML -> MonikerPatch::BindToStorage.
-//   (IEFrame starts this by calling mshtml!*SuperNavigate*)
-//    - request_data is NULL
-//    - check if the url is a top level url
-//    - iff the url is a top level url, we switch in our own callback object
-//      and hook it up to the bind context (BSCBStorageBind)
-// - BSCBStorageBind::OnDataAvailable - sniffs data and determines that the
-//   renderer is chrome. It then registers a special bind context param and
-//   sets a magic clip format in the format_etc. Then goes into pass through
-//   mode.
-// - mshtml looks at the clip format and re-issues the navigation with the
-//   same bind context. Also returns INET_E_TERMINATED_BIND so that same
-//   underlying transaction objects are used.
-// - IEFrame -> MonikerPatch::BindToStorage
-//    - We check for the special bind context param and instantiate and
-//      return our ActiveDoc
-
-//
-// Scenario 3: CF navigation through mshtml link
-//  Same as scenario #2.
-//
-
-//
-// Scenario 4: CF navigation through link click in chrome loads non CF page
-// - Link click comes to ChromeActiveDocument::OnOpenURL
-//    - web_browser->Navigate with URL
-// - [Scenario 1]
-//
-
-//
-// Scenario 5: CF navigation through link click in chrome loads CF page
-// - Link click comes to ChromeActiveDocument::OnOpenURL
-//    - web_browser->Navigate with URL
-// - [Scenario 2]
-//

-// This class is the link between a few static, moniker related functions to
