Erreur lors d'une redirection Apache

Bonjour,

Je souhaite faire une redirection au niveau de mon serveur Apache pour proposer un contenu propre au mobile.

Ma redirection commence bien : Apache transforme comme je veux l'url '/~simon/tests/omega' en '/~simon/tests/omega/m'.

Par contre, à l'étape suivante, il transforme l'url '/~simon/tests/omega/m' en fichier local '/Users/simon/tests/omega/m' ce qui entraîne une erreur.

En effet, mon Apache tourne sur un Mac, et l'url '/~simon/tests/omega/m' devrait correspondre au fichier '/Users/simon/Sites/tests/omega/m'.

Qu'est-ce qui cloche à votre avis?

Pour info, extrait du httpd.conf :

---
RewriteEngine on

#redirect mobile browser using HTTP_ACCEPT header
RewriteCond %{HTTP_ACCEPT} "text/vnd.wap.wml|application/vnd.wap.xhtml+xml" [NC]
RewriteCond %{HTTP_HOST} "!/tests/omega/m" [NC]
RewriteRule (.*)/tests/omega(.*) $1/tests/omega/m$2 [L]

#some high-end phone sometimes support HTML, only its sucks
#add more browser user agent sig here
RewriteCond %{HTTP_USER_AGENT} (nokia|symbian|iphone|blackberry) [NC]
RewriteCond %{HTTP_HOST} "!/tests/omega/m" [NC]
RewriteRule (.*)/tests/omega(.*) $1/tests/omega/m$2 [L]

Et les logs d'Apache :
