Is it possible to set Apache’s AllowOverride directive to All

The AllowOverride directive in the Apache's configuration has been set to ‘All’ on all Siteground servers.

Thus you are able to use a local .htaccess file and define options such as:

#Enable mod_rewrite and insert some sample rules:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
#RewriteCond %{REQUEST_URI} ^(/component/option,com) [NC,OR]         ##optional - see notes##
RewriteCond %{REQUEST_URI} (/|.htm|.php|.html|/[^.]*)$  [NC]
RewriteRule ^(content/|component/) index.php

#Enable security mod:
SecFilterEngine On
SecFilterScanPOST On
# SecAuditLog logs/audit_log # Not sure what my host would think of that...
SecFilterDefaultAction "deny,status:412"
# WEB-ATTACKS wget command attempt
SecFilterSelective THE_REQUEST "wget "

#Set different handlers for scripts:
AddHandler nonworkig .cgi .pl .py

Note: Please do not use an .htaccess file to specify PHP settings. PHP settings can be changed only with a local php.ini file.
