Import/include external VirtualHost files from directory to be used inside Apache's httpd.conf

Question

Would there be a solution to import all files with virtual host records in to httpd.conf ?

For single file this solution works fine:

include domain1.conf
include domain2.conf
include domain3.conf

But can't find the solution to include all files from a particular directory, I tried

include  /etc/httpd/conf/vhosts/*

but dos not seems to be reading anything from /etc/httpd/conf/vhosts/

Answer 1

Add extension of configuration file names by example:

include  /etc/httpd/conf/vhosts/*.conf

And check files and directory permissions at /etc/httpd/conf/vhosts. Apache user must have permission to read all from this directory.
