Here is what I tried in a .htaccess file in my virtual host's document
root:

RewriteCond {SCRIPT_FILENAME} !^membersignin$ [NC]
RewriteCond {HTTP_HOST} ^([^\.]+)\.mydomainname\.com [NC]
RewriteRule ^(.*)$ http://mydomainname.com/membersignin/?userid=%1
[R=301,QSA,NC,L]

This works great for:

http://www.mydomainname.com/

which is rewritten to:

http://mydomainname.com/membersignin/?userid=www

But;

http://dhhoyle.mydomainname.com/

gets a Page Load Error, looking for dhhoyle.mydomainname.com.

That is, no rewrite took place!

This is my first attempt at using mod_rewrite. Any help would be
appreciated.

Thanks,

Danny

That would suggest that either:
you don't have DNS for *.mydomainname.com
or your virtual host entry doesn't contain
ServerAlias *.mydomainname.com
