* MM_FlashInfo() -- construct an object representing Flash Player status
*
* Constructor:
*
* new MM_FlashInfo()
*
* Properties:
*
* installed true if player is installed
* (undefined if undetectable)
*
* implementation the form the player takes in this
* browser: "ActiveX control" or "Plug-in"
*
* autoInstallable true if the player can be automatically
* installed/updated on this browser/platform
*
* version player version if installed
*
* revision revision if implementation is "Plug-in"
*
* Methods:
*
* canPlay(contentVersion) true if installed player is capable of
* playing content authored with the
* specified version of Flash software
*
* Description:
*
* MM_FlashInfo() instantiates an object that contains as much
* information about Flash Player--whether it is installed, what
* version is installed, and so one--as is possible to collect.
*
* Where Flash Player is implemented as a plug-in and the user's
* browser supports plug-in detection, all properties are defined;
* this includes Netscape on all platforms and Microsoft Internet
* Explorer 5 on the Macintosh. Where Flash Player is implemented
* as an ActiveX control (MSIE on Windows), all properties except
* 'revision' are defined.
*
* Prior to version 5, Microsoft Internet Explorer on the Macintosh
* did not support plug-in detection. In this case, no properties
* are defined, unless the cookie 'MM_FlashDetectedSelf' has been
* set, in which case all properties except 'version' and 'revision'
* are set.
*
* This object is primarily meant for use by MM_FlashDispatch(), but
* may be of use in reporting the player version, etc. to the user.

* MM_FlashDispatch() -- get Flash Player status and redirect appropriately
*
* Synopsis:
*
* MM_FlashDispatch(contentURL, contentVersion, requireLatestRevision,
* upgradeURL, install, installURL, altURL,
* overridePluginsPage)
*
* Arguments:
*
* contentURL URL of document containing Flash content
*
* contentVersion version of Flash software used to
* author content
*
* requireLatestRevision Boolean indicating whether to require
* latest revision of player (plug-in only)
*
* upgradeURL document to load if player must be
* upgraded to play content and automated
* updating is not supported on the user's
* browser & platform
*
* install Boolean indicating whether to install
* if player is not installed
*
* installURL document to load if 'install' is true
* and automated installation is not
* supported on user's browser & platform
*
* altURL document to load if 'install' is false
*
* overridePluginsPage Boolean indicating whether to set the
* PLUGINSPAGE attribute for the embedded
* Flash Player sniffer to `installURL'
* disableAutoInstall Boolean indicating that the auto-installation
* should not occur and that the user will go to the installURL
* or to the upgradeURL as specified
*
* Returns:
*
* Normally, never returns; changes window.location.
* Returns with no value when called improperly.
*
* Description:
*
* MM_FlashDispatch() detects whether the user's Web browser has the
* Flash plug-in or ActiveX control installed, and what version is
* installed if so. It then takes appropriate action based on whether
* Flash Player is installed and is compatible with 'contentVersion':
* load a document containing Flash content, load alternate content,
* or oversee the updating or installation of the player.
*
* There are three possible outcomes of the detection process:
*
* 1. A version of Flash Player has been detected that is
* suitable for playing the requested content version.
* MM_FlashDispatch() will load 'contentURL'.
*
* 2. An unsuitable version of Flash Player has been detected.
* MM_FlashDispatch() will load 'contentURL' if automated
* updating is supported on the user's browser & platform;
* otherwise, it will load 'upgradeURL'.
*
* 3. Flash Player is not installed. If 'install' is set to
* true, MM_FlashDispatch() will load 'contentURL' if the
* user's browser supports automated installation; otherwise,
* it will load 'installURL'. If 'install' is false,
* MM_FlashDispatch() will load 'altURL'.
*
* When script-based detection of Flash Player is not possible,
* MM_FlashDispatch() attempts to load a Flash movie to carry out
* the detection. If Flash Player is not installed, there is presently
* no choice but to let the browser redirect the user via the
* PLUGINSPAGE attribute of the EMBED tag. In this case, 'install'
* is ignored, but setting 'overridePluginsPage' to true will
* set PLUGINSPAGE to 'installURL', overriding its default value
* (the URL for the Macromedia Flash download center). If this flag
* is set, 'installURL' must be absolute, not relative.
