 Client/Server Gateway JSAPI

 Author: Dan G. Switzer, II
 Date:   December 08, 2000
 Build:  203

 Description:
 This library provides the foundation for easily creating a communication
 gateway between the client and a server.

 With this library you'll be able to push and recieve information from
 the server, inline to the page.

 Version History
 ---------------
 Build 203 (July 24, 2003)
 - Added the GatewayAPI.build property
 - Added the iframeSrc attribute. It seems that on HTTPS
   IE was throwing a message complaining about secure and
   unsecure items running on the page together. If you're
   running SSL/HTTPS on the site, just set this property
   to a blank html document. I'm including one with the
   build you can use.
 - Added the LGPL to the build. Some asked me about
   licensing for the code.

 Build 202a (March 14, 2003)
 - Released the code w/an unused function I used for debugging
   as well as I forgot to update the build number in the comments.
   No real changes.

 Build 202 (March 14, 2003)
 - Opera 5 does not properly cache the variables--it seems to
   make pointers to the iframe, so once a page is reloaded
   the references no longer exist. To work around this problem
   caching is turned off automatically for Opera 5.
 - Fixed bugs causing Opera 5 & 6 not to work. In order for
   Opera to reload a document into an iframe, the iframe tag
   needed a src attribute
 - Removed the script tag that was trying to load the wddx library.
   This wasn't used anyway and was the result of some legacy code.
   This was causes problems in NS4.7x.

 Build 201 (March 12, 2003)
 - Added caching routine. Caching is enabled by default. You can
   either turn caching off completely setting the obj.enableCache
   to false, or you can overwrite the cache settings per call
   to the server using the obj.sendPacket(value, useCache) argument.

 Build 200 (March 10, 2003)
 - Rewrote majority of API

 Build 104 (December 20, 2000)
 - Made the status bar updatable by changing the hard code delay to a var
   (this.statusdelay)
 - Changed delay of status bar updates from 10 to 100

 Build 103
 - Added catch for testing whether or not the WDDX library was actually loaded
   if it's not, we warn the user and disable the gateway.
 - Changed the name of the disable variable to disabled
 - Added onTimeout prototype for defining a function to run if the event times
   out

 Build 102
 - First release
