HP-UX 11i NSA HTTP Software
Announcement
The HP-UX NSA HTTP product enables NSA (Network Server Accelerator) functionality for
HTTP on HP-UX 11i. NSA HTTP provides a new feature for the HTTP protocol: the ability to
service URI requests from a data cache in the kernel. Because web page requests no longer
have to be passed to a user space HTTP application, NSA HTTP vastly improves Web server
performance.

NSA HTTP User Interface Command
HP-UX 11i NSA HTTP provides the nsahttp user interface command. This command can be
used to display statistics on the TCP ports registered to use NSA HTTP, and other
configuration and statistical information. This includes:
• The total number of TCP connection requests received for the registered NSA HTTP
ports.
• The number of HTTP cache hits, which corresponds to the number of HTTP GET requests
that NSA HTTP serviced from its cache.
• The number of HTTP cache misses, which corresponds to the number of HTTP GET
requests that NSA HTTP could not service from its cache.
• The current size of the HTTP cache in bytes.
