Apache and the trailing slash problem

In: , , , , On: 2004 / 05 / 08 Short URL: http://ozh.in/z

On badly configured Apaches (like on errr… my host :), URLs referecing directories and lacking a trailing slash (like /mydir instead of /mydir/) lead to an error : the webserver looks for a file named mydir instead of a directory.

After some googling and lots of testing, I've come up with a solution. This should even work on Apaches with virtual hosts enabled and bad ServerName directive.

Put this in .htaccess in your document root (given example is for my site of course, replace the server name with yours)

< View plain text >
code

  1. RewriteEngine  on
  2. RewriteBase    /
  3. RewriteCond    %{REQUEST_FILENAME}  -d
  4. RewriteRule    ^(.+[^/])$           http://frenchfragfactory.net/$1/  [R=301,L]

Of course, you need mod_rewrite and the ability to override these settings in your .htaccess file.

Je déteste Paris

Ariane et Ozh à Paris
A friend sent me this picture from last year, August, in Paris. This is funny how my wife and I look like happy tourists since I absolutely hate this town. Soon or later I will have job offers in this city : I absolutely have to remember how much I dislike it, more than any advantage a job may have.
Don't even know if that ever makes sense in english by the way :)

404 et traduction

In: , , , On: 2004 / 05 / 04 Short URL: http://ozh.in/w

I'm still playing a bit with my new layout.

I've added a css-javascript-cookie-based (thus, client side) solution for my bilingual needs. Errr. Wishes. Whatever. So, where available, you can display things in English flavor or in French taste (including potential mistakes since I'm not as fluent as I should after 13 years of english classes:)
Also, if you know a bit of French culture and its old cars, I hope you will enjoy my 404 not found page. G'night.

Welcome to the third version of my site !

The alpha version of my personnal site was an uberugly page on Compuserve in 1995, with enough animated gifs and background to overload my 33.6k connection :) Version 1 was a regular static html site, which you still can visit from the link above. Version 2 didn't really existed but was splitted in various places : code pieces were on a static page, then using Thought Bucket, and my rants and articles were written on a French Quake Community site I run.

This site now uses WordPress, an excellent "blogware" in my opinion. Well. Of course. Wouldn't be using it if I thought it sucked. As of today, the blog / news / main page, whatever you call it, is functionnal, but I still have to set up other pages.

I plan to store here mainly pieces of code I don't want to forget, maybe a few thoughts from time to time, most probably written in French, perhaps a few pictures. But primarily scripts. And don't expect everything to be both in French and English :)

Fake perl shell

This script emulates a (really ugly) perl shell within your bash (or wathever) session. I like it to quickly test a few regexps or a function.
