A few syntax tweaks:

SetEnv abc Test
#
RewriteCond %{ENV:abc} ^Test$
RewriteRule (.*) dir/file.html [L]

Thanks Jim for reply

SetEnv abc Test
#
RewriteCond %{ENV:abc} ^Test$
RewriteRule (.*) dir/file.html [L]

:) Thanks to you Jim,

The following piece of code worked for me.

SetEnvIfNoCase Host www\.abc\.com abc=set
RewriteCond %{ENV:abc} set
RewriteRule (.*) dir/file.html [L]

But the following is not working.

SetEnv abc Test
#
RewriteCond %{ENV:abc} ^Test$
RewriteRule (.*) dir/file.html [L]
