[ne07]

Need assistance with rewrite rule alternative for SetEnvIf directive

SetEnvIf Host ^.? site_host=default
SetEnvIf Host ^(.+) site_host=$1
SetEnvIf X-Forwarded-Host ^(.+) site_host=$1

something similar to :

Above rewrite rules work perfectly on the Apache system, please guide us how to implement the same on the LS system. Thanks!

RewriteCond %{HTTP_HOST} ^(.?)$
ReriteRule .* [E=site_host:default]

RewriteCond %{HTTP_HOST} ^(.+)$
ReriteRule .* [E=site_host:%1]

RewriteCond %{HTTP:X-Forwarded-Host} ^(.+)$
ReriteRule .* [E=site_host:%1]
