There's only a week left to register for the O'Reilly
Open Source Convention 2000. Monterey, California plays
host to the conference between July 17th and 20th, and brings
together the leaders of 10 critical open source technologies
- including Apache - to give you an inside look at how to
configure, optimise, code, and manage them.
Apache Week will be there, along with notable Apache members
on the list of speakers. If that doesn't tempt you there is
also a feast of activities including the Double Feature Movie
night, the Open-Source Caribbean Jam, and the "Buy the Apache
Week team a Beer" night. Okay, so we made the last one up.
Each month we report on the new figures from the Netcraft and E-Soft surveys of web
sites. Both surveys show similar results with Apache far in
the lead, as they follow similar methods for collecting their
data. This month Netcraft show Apache and Apache-based
servers have over 65% of the market share of standard sites,
and E-Soft shows Apache at 62% of secure sites.
Because both these popular surveys look at every domain
available, they are easily biased by ISPs and companies that
give away lots of free virtual domains such as Namezero. Other surveys,
such as one from BizNix choose to
take a smaller sample such as companies in the Fortune 500
list. These surveys have always tended to favour Microsoft
and Netscape servers.
This week the Sunday Times published their list of the top
100 privately owned European e-businesses. UK IT news site,
The Register, has an interesting
commentary on the top 10 from the list, so Apache Week
decided to jump on the survey bandwagon to see what servers
these companies run on their public-facing sites. The results
show that four of the sites are running Apache-based servers
on Unix, three run Netscape Enterprise, and the remaining
three are Microsoft IIS.
In the news this week is a new web server called "TUX"
written by Red Hat. TUX is an in-kernel web server and is
embedded into the Linux OS. In-kernel servers are not a new
idea, with IBM shipping their HTTP
Get Engine for AIX that can interface with Apache. The
idea is that simple requests, such as requests for static
content, can be parsed and fulfilled completely in kernel
space that dramatically improves performance. With an
in-kernel cache, any request that cannot be handled by the
kernel is transparently passed on to a user-space web server.
The response from the server is then cached in the kernel
According to one of the authors in a
discussion on Slashdot, "'TUX' comes from 'Threaded
linUX webserver', and is a kernel-space HTTP subsystem. TUX
was written by Red Hat and is based on the 2.4 kernel series.
TUX is under the GPL and will be released in a couple of
weeks. TUX's main goal is to enable high-performance
webserving on Linux, and while it's not as feature-full as
Apache, TUX is a 'full fledged' HTTP/1.1 webserver supporting
HTTP/1.1 persistent (keepalive) connections, pipelining, CGI
execution, logging, virtual hosting, various forms of
modules, and many other webserver features. TUX modules can
be user-space or kernel-space. "
The author also claims that "We expect TUX to be
integrated into Apache 2.0 or 3.0", although this idea
hasn't yet been discussed with the Apache group and is highly
unlikely to happen for Apache 2.0.
A new protocol, BXXP, has been developed and is touted to be
on steroids". One of the features of BXXP is that a
single connection can carry multiple simultaneous exchanges
of data, which is ideal for exchanging meta-data. The news
story goes on to quote that "the odds are good that BXXP
will be bundled in the next version of Apache, which is due
out this fall," although it has yet to be discussed with
the Apache group and no patches have been submitted.
