The ComfortASP.NET V0.51 AJAX framework was just released with the following improvements:

- Added: Caching of client scripts to reduce traffic
- Added: Control granularity of diff engine to balance traffic and CPU load
- Added: Possibility to turn on a feature to prevent IE Memory leak
- Added: Support for IE7 (Beta2)
- Added: The following configuration properties:
       AutoFocusEventTarget
       CachePageScripts
       IEMemoryLeakWorkaround
       DiffGranularity
       StaticReferencedScripts
- Fixed: SetFocus functionality refactored
- Fixed: Performance of diff engine was optimized

After looking at IE7 Beta 2 I was scared watching the memory consumption in the task manager. Microsoft hasn't fixed this really bad issue of IE6 not, yet. I hope that the final version of IE7 will be a little bit more AJAX friendly and cleans unused elements - even after using innerHTML ;-)
Until then, I have added a further option called "IEMemoryLeakWorkaround" to clean most of the unused elements in IE6/7 after a hidden postback. This can be a hard task for a script for big web pages - so the  "IEMemoryLeakWorkaround" option is turned off by default. You can turn this on, until Microsoft takes the memory leackage pain of out of IE. Many thanks go to Michael Schwarz  for chatting with me about this topic several times and giving me the required hints!

I am really happy to present this release, because it completes my long targeted feature list of reducing traffic for ASP.NET pages to an absolute minimum without programming AJAX directly by doing the following things automatically:
- Detect and transfer only HTML changes
- Detect and transfer only changed inline page scripts
- Caching of ComfortASP.NET framework stuff
- Caching of referenced (external) page scripts
- Compression of postback data
So under the line there are no more great possibilities to reduce traffic (automatically with a framework) in my mind. Please compare yourself by using the Fiddler HTTP debuggin proxy with your pages by turning ComfortASP.NET on/off. If you have further ideas of reducing traffic, please drop me a note!

I hope you enjoy the "non-invasive" AJAX framework ComfortASP.NET, because I think it has reached a considerable level with this release - allthough it is still beta and has to be optimized. Don't hesitate to register for the full version. It's free for everyone to use!
