Apache Quick Reference Card

I have updated my quick reference card for the Apache server for Apache version 1.3.3.

News
(18 October 1998) revision 1.1 of the card has been released covering version 1.3.3.
Also I have put together the bones of a mod_perl quick reference card.
(4 August 1998) revision 1.0 of the card has been released. This revision covers version 1.3.1 of Apache (two new directives and a couple of new command line options). I have had no reports of errors so I am calling this one revision 1.0.
(24 June 1998) revision 1.3.0-0.4 of the card has been released. This corrects errors in previous revisions that marked all directives as being extensions! (due to a typo in the perl script that generated the card).
(16 June 1998) revision 1.3.0-0.3 of the card has been released. New in this revision are the inclusion of Apache-SSL directives, a list of all HTTP 1.1 status codes and a couple of minor corrections and typographical changes.
(10 June 1998) an announcements mailing list has been set up (see below).

The card is available here as PostScript and PDF files in three different versions (about 25KB for the PostScript and 70KB for the PDF):

single column format for A4 or US letter paper	PostScript
triple-fold format for A4 paper	PostScript
triple-fold format for US letter paper	PostScript

For the technically inclined: the single column format card is generated from a database of directives using a custom Perl script, formatted with LaTeX at 11pt using Times and a condensed Courier font and then converted to PostScript with dvips. The triple-fold A4 and US letter versions are created by manipulating the individual pages of the PostScript output from the single column version using pstops. The PDF versions are converted from PostScript using GhostScript.

Any comments on how to improve the contents of the card or on its usefulness would be greatly appreciated.

Automatic log file rotation

I have also written an alternative automatic log file rotation program, called cronolog that works with Apache. Cronolog always writes to a current log file, the name of which is constructed from a template using the current date and time. The template uses the same format specifiers as the Unix date command (which are the same as the standard C strftime library function). For example specifying:

    TransferLog   "|/usr/local/sbin/cronolog /web/logs/access-%Y-%m-%d.log"

would write access log files with names like access-1998-06-09.log (creating a new log file each day at midnight).
