You can now download IISxpress 2.1 for Windows Vista, 2003, XP and 2000 from the download area. This version will also install and run on Windows Server "Longhorn" Beta 3 (build 6001).
The major features of this release are:
- Now supports Windows Vista RTM and Windows Server "Longhorn" Beta 3.
- Compression Cache - static content will be stored in the cache allowing for very fast compressed responses.
- User-definable CPU Loading Model - on a multi-CPU system you can specify which CPU cores are used for compression tasks.
- Update check - check that you have the latest version of the software.
- The installer and all binaries are now signed to prevent tampering.

The compression cache stores the most recent compressed responses. You can specify the size of the cache and the number of responses to store. Responses served from the cache can be up to 10 times faster than a full compression pass.

Specify the way IISxpress uses your CPUs for compression tasks. Select from Automatic, Manual or None. In Automatic mode IISxpress will allocate a CPU for each response. In Manual mode you specify which CPU cores IISxpress is allowed to use. When None is selected the Operating System manages the division of the compression tasks.

When you use IISxpress you can control which parts of your web sites are compressed. Here all the folders below FlexWiki will not be compressed (they are shown in red).
