Sending Cache-control Headers Using Apache 2.x and mod_expires

About a year ago I wrote about how use mod_header with Apache 1.3x to send Cache-control headers. It worked so well that I want to configure my Apache 2.x servers to send the same headers. It's even simpler with Apache 2.x since mod_expires is included in most default installs. Here's what I did.

I added a configuration directive for the main server configuration (inside the Directory block) which sends the Cache-control header for common graphics.

Automated Backups of Filemaker Server 6.0 running on Linux

When running Filemaker Server 5.5/6.0 on Linux one looses the nice automated backup features which exist in the Windows and Mac versions of the software. It turns out backups can be automated pretty simply by using the PAUSE and RESUME options for fmserverd. I don't claim to be a super bash scripter but here's an example script to get you going (keep in mind that this script lacks error handling, use it at your own risk). NOTE: If anyone would like to add error handling and other nifty features please login and post a comment with your suggestions.

Running Filemaker Server 5.5/6.0 on SuSE 9.3

I have recently configured Filemaker Server v5.5/6.0 to run on SuSE 9.3 using the techniques outlined in the How To "HowTo run Filemaker Server 5.5 on Redhat Linux 7.3, Redhat Linux 9.0 and Redhat Fedora Core 1" authored by Christof Baumgärtner. The key ends up being the compat-glibc-6.2- (glib 2.1 compatibility) libraries. Filemaker Server on Linux is a good alternative to server proliferation. Now I can consoludate Filemaker services onto our existing Linux infrastructure without having to buy yet anoth

Sending Cache-control Headers Using Apache's header module

NOTE: If you're using Apache 2.x go here.

I manage a fair number of Apache 1.3x web servers. Most of which are used for virtual hosting. After reading an article by Jeff Fulmer in SysAdmin Magazine entitled "Save Bandwidth and Increase Performance with Cache-control Response Headers" I decided to configure my Apache servers to use mod_header to send the Cache-control header for graphics files.

Using Spamassassin with Qmail

I've been using Qmail for some time now and like it quite a bit. I recently configured a new Qmail server and wanted to set it up to use Spamassassin on a per user basis. I used to use ifspamh to do this but for some reason it would not work properly on my new server. While I was looking for a fix I came across a better way.

Killing spam while using the Qmail MTA

Chris Hardie's Qmail Anti-Spam HOWTO is a good resource. You will find this to be quite thorough. Georg Lehner has written "How to use Spamassassin together with Qmail." In it Georg describes how to setup Qmail with Spamassassin to meet your needs. You should also checkout Vipul's Razor: Vipul's Razor is what you now commonly know as SpamNet.
