Internal handling of subdomains

[StijnH]

Hello,

there seems to be an issue with subdomains and how they are handled by DirectAdmin.
The issue is with mod_rewrite, but seems to be a .htaccess problem.

Please see the following thread for all information (+ 'solution' from mod_rewrite): http://forum.modrewrite.com/viewtopic.php?t=37576

Well, it's not really an issue. Using "$1" is wrong because the .htaccess file get parsed in the domain directory, not the subdomain one, so in RewriteRule the "^(.*)$" regular expression is "/subdir/..." instead of the original request "/...".

There is no "corruption by internal processing" like that poster said. "$1" doesn't work just because the subdomain resides in the directory of the domain, and .htaccess files are recursive. Apache tries to read any .htaccess file present in all the parent directories of any document root.

Using "%{REQUEST_URI}" to redirect a website is the only correct way, even if the backreference "$1" works most of the time.

Thank you for the clarification.

I was pretty confused about it, cause both no-www.org and mod_rewrite FAQ use "$1".
I'll pass the message

If you add the subdomain as a regular domain then you do not have those issues.
