Not working in advanced app for me

[kaptnkage]

Ive checked your main component and found setWebroot section thinking this is where I could hack it in my config/bootstrap.php making an alias for webroot to no avail.

here is my apache conf
"bty" is like my backend

on frontend everything compresses fine

any help?

Alias /bty "/Server/BTY/web/bty"
<Directory "/Server/BTY/web/frontend">
<IfModule mod_php5.c>
php_value include_path "/Server/BTY/app"
php_admin_flag engine on
</IfModule>
<IfModule mod_rewrite.c>
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
</Directory>
<Directory "/Server/BTY/web/bty">
<IfModule mod_php5.c>
php_value include_path "/Server/BTY/app"
php_admin_flag engine on
</IfModule>
<IfModule mod_rewrite.c>
RewriteBase /bty/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]
</IfModule>
</Directory>

here is my bty/config/bootstrap.php
@bty is my main app folder
Yii::setAlias('web', '@BTY/web/bty/');
Yii::setAlias('webroot', '/');
