The FreeBSD Web server will move from hub to freefall next week. The
new web server is already installed and runs on
http://freefall.freebsd.org. There are several reasons for the move:

1. hub is overloaded with non-interactive mail traffic. Dozens
   sendmail processes require all available memory and any
   cgi script wake up the pagedaemon.

2. disk i/o is sometimes awfully slow on hub - e.g. 20 seconds
   for `man man'

3. Many disk i/o havy cgi scripts (gnats, cvsweb,ports) read
   data over NFS from freefall. I guess 1/2 up to 1GB/day.


The new server runs apache version 1.3beta7 and use the new reverse
proxy feature (*). This feature enable load balancing and distributed
HTTP traffic by URL (sic!).

Currently freefall transparently forwarded the cgi scripts 
^/cgi/(getmsg|search|mid|reg|url|dosendpr|gallery)(.cgi.*)
to http://hub.freebsd.org/cgi/<script>;
The other cgi scripts (query-pr, cvsweb, ports, man) and
the static html pages are handled locally on freefall.

This should dramatically reduce the NFS traffic between
hub and freefall. All cgi scripts runs now on local disks.

Please test the new server and report any bugs (especially
not properly working cgi scripts) to webmaster@freebsd.org
