I am using apache 2.2 and I need to have certain http requests (those including example.com for instance) to be executed normally and forwarded to another server.
With mod_rewrite, I could easily forward but then the input request would not be executed on my server. Right?

NAME
nca, snca - the Solaris Network Cache and Accelerator (NCA)
The Solaris Network Cache and Accelerator ("NCA") is a kernel module designed to provide improved web server performance. The kernel mod-
ule, ncakmod, services HTTP requests. To improve the performance of servicing HTTP requests, the NCA kernel module maintains an in-kernel
cache of web pages. If the NCA kernel module cannot service the request itself, it passes the request to the http daemon (httpd). It uses
either a sockets interface, with family type designated PF_NCA, or a private Solaris doors interface that is based on the Solaris doors RPC
mechanism, to pass the request.
To use the sockets interface, the web server must open a socket of family type PF_NCA. The PF_NCA family supports only SOCK_STREAM and pro-
tocol 0, otherwise an error occurs.
The following features are not presently supported:
o You cannot initiate a connection from a PF_NCA type socket. The connect(3SOCKET) interface on PF_NCA fails.
o System calls that are associated with type SO_DGRAM, such as send(), sendto(), sendmsg(), recv(), recvfrom(), and recvmsg(), fails.
o You cannot set TCP or IP options on a PF_NCA type socket through setsockopt(3SOCKET).
The NCA cache consistency is maintained by honoring HTTP headers that deal with a given content type and expiration date, much the same way
as a proxy cache.
For configuration information, see
When native PF_NCA socket support does not exist in the web server, the ncad_addr(4) interface must be used to provide NCA support in that
web server.
NCA is intended to be run on a dedicated web server. Running other large processes while running NCA might cause undesirable behavior.
NCA supports the logging of in-kernel cache hits. See ncalogd.conf(4). NCA stores logs in a binary format. Use the ncab2clf(1) utility to
convert the log from a binary format to the Common Log File format.
/etc/nca/ncakmod.conf Lists configuration parameters for NCA.
/etc/nca/ncalogd.conf Lists configuration parameters for NCA logging.
/etc/nca/nca.if Lists the physical interfaces on which NCA runs.
/etc/nca/ncaport.conf ncaport configuration file
/etc/hostname.{}{0-9} Lists all physical interfaces configured on the server.
/etc/hosts Lists all host names associated with the server. Entries in this file must match with entries in /etc/host-
name.{}{0-9} for NCA to function.
