Bugs in 1.2.4:
Release: 1.2.4 (Released 22nd August 1997) (local download
Alpha: 1.3a1 (Released 23rd July 1997) (local download
Apache can be configured to set some environment variables
to work-around certain bugs, such as
force-response-1.0. This variable (if set)
will also be passed onto child CGI programs, but it is not
a valid variable and some shells will complain about it.
Bugs fixed in 1.3:
Apache will send an ETag with SSI documents accessed by
XBitHack. This is harmless but not compliant with HTTP/1.1.
A name based virtual host can be accessed from a request to
a different port number to the one associated with the
Adding modules with LoadModule (Windows only)
could cause memory corruption if too many modules were
added, or if LoadModule is placed not at the
top of httpd.conf.
Fix bug when timeouts occur under inetd mode (although
inetd mode is not recommended and may not work properly
Work around problem on Linux where a child can loop rather
then realise that a new connection is available
Added support for Unisys SVR4
Apache 1.2.4 is the current stable release. Users of Apache
1.2.3 and earlier should upgrade to this version. The next
release will be 1.3. The first beta of 1.3 will be available
shortly. An alpha test release of 1.3 is available now for
compilation and testing on Windows 95 and NT systems.
Patches for bugs in Apache 1.2.4 may be made available in the
to 1.2.4 directory on the Apache site. Some new features
and other unofficial patches are available in the 1.2
patches directory. For details of all previously reported
bugs, see the Apache bug database and
bugs pages. Also many common configuration questions are
answered in the Apache FAQ.
All the Apache source code has been formatted into the
standard Apache style. Previously the code has contained a
mix of styles, depending on who authored particular bits.
Recently a discussion was held amongst the developers to
decide on a single, consistent style for Apache code. Various
types of layout were voted upon, and the most popular styles
used as the Apache style. A set of arguments for "indent" was
created, and all the source code was run through indent. The
result was then manually checked to ensure that indent got
the layout correct (it sometimes did not).
The module API includes a function called
set_last_modified() which sets the
Last-Modified header to be returned to the
client. It also generates an ETag, which is used by HTTP/1.1
clients to cache responses. In some cases ETags should not be
added, but Last-Modified should. So there is now a new API
function, set_etag() which sets just the ETag
value, and set_last_modified() no longer creates
As part of these changes there is another new function,
meets_condition which can be used to check that
the intended response meets any pre-condition in the request
(for HTTP/1.1 requests). This function is used by mod_cgi, so
it means that CGI programs can now output ETag information
which will be subject to HTTP/1.1 conditions. If the response
does not meet the condition, Apache will return the
appropriate HTTP/1.1 response code, and ignore the body of
PC Week briefly mentions Apache in an article on building a
free internet server, based on FreeBSD. The article is at Nothing's
free, but intranet comes close.
