release notes
Announcement
The HP-UX Network Server Accelerator (NSA) HTTP B.11.31.01.03 product enables
NSA functionality for the HTTP protocol on HP-UX 11i v3. NSA HTTP improves web
server performance by maintaining an in-kernel cache of recently accessed web pages.
When NSA HTTP is activated, the web page requests (HTTP GET requests) are serviced
directly from the data cache in the kernel. Serving web pages from the in-kernel cache
instead of passing the requests to a user-space application greatly improves the web
server performance.
What’s new in this version
NSA HTTP B.11.31.01.03 includes the following new feature:
Starting with this version, NSA HTTP is not activated automatically. Instead, the user
needs to activate it manually. For information on the manual steps, see “Installing,
activating, and configuring NSA HTTP” (page 7).
It also contains the defect fix for QXCR1000912788. For more information, see “Known
problems and workarounds” (page 9).

• Support for HP-UX 11i v2
• Virtual web server support

facto industry standard used by many web server vendors
