How to redirect to and from SSL in Apache

by Jeremy on Aug.05, 2010, under Linux

So … you have an e-commerce checkout page or a secure login thusly giving you the need to have an SSL page. But you don’t want people then staying in SSL the whole time, and adding an additional burden to your servers, do you? Here’s the simple solution, using mod_rewrite. The following two code snippets go into your apache virtualhost config files. This varies quite a bit by distro, but in Gentoo they’re in /etc/apache2/vhosts.d/

For the SSL virtualhost, add the following (between its tags obviously…)

RewriteEngine On
RewriteCond %{HTTPS} on
RewriteCond %{THE_REQUEST} !^[A-Z]{3,9}\ /(.*)TheEndOfTheURLOfPageToRedirect\.html\ HTTP/ [NC]
RewriteRule ^/(.*) http://%{SERVER_NAME}%{REQUEST_URI} [R]

This will redirect down from SSL all pages except those precious SSL needed pages. Just add additional lines like the 3rd if you have multiple pages that need SSL.

Now add the following to the regular non-SSL Virtualhost entry for the same site:


RewriteEngine On
RewriteCond %{HTTPS} !on
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /(.*)TheEndOfTheURLOfPageToRedirect\.html\ HTTP/ [NC]
RewriteRule ^/(.*) https://%{SERVER_NAME}%{REQUEST_URI} [R]

The Lost Art of the Friday Work Whistle

by Jeremy on Jul.13, 2010, under Uncategorized

Call it the 5 o’clock whistle. The 5 o’clock send off. The weekend blastoff. The weekend work whistle. The Friday work whistle. Whatever. The point is, hardly anybody does this anymore, and it’s a shame. Below are the ONLY specimens I can find that aren’t some lame DJ blowing a referee’s whistle… but REAL Friday work whistles. Enjoy!

[EDIT: Update! Since apparently I'm not the only person interested in this (I made it on Reddit! Holy cow!) ... I am now offering an updated rapidshare link with NEW whistles, and them all put into one .zip archive.]

It contains all the following:
1) WMXT 102.1 The Fox — Florence, SC — Better start, more music.

2) WROQ Rock 101.1 — Greenville, SC — Longer, more mixed in clips.

3) WKLS 96Rock — Atlanta, GA — The predecessor to 102.1′s version.

4) WHTZ Z-100 — New York City, NY — The version they did in 1984!

5) NEW!! Adam Curry – The Daily Source Code – Fubar Friday (short)

6) NEW!! WNKS KISS 95.1 — Charlotte, NC – Weekend Blast (short)

7) NEW!! WKLS Project 961 — Atlanta, GA — The ALL NEW version airing currently!

Here I go, lowering standards elsewhere

by Jeremy on Jun.20, 2010, under Linux

Stephen Spector, Community Manager for Xen, as well as a speaker and exhibitor at the 2010 Southeast Linuxfest, made the mistake of interviewing me. Apparently nobody told him I’m not actually important.

You can watch more interviews at SELF, and got a whole bunch more open source goodness, at Stephen’s blog Open Source Exposed over at Network World.
