[users@httpd] How to skip setting HSTS header for certain virtual hosts only?

[Eddie B]

I set HSTS for HTTPS only, using this directive at the beginning of httpd.conf 
(apache 2.2)

 

<IfModule mod_headers.c>

Header add Strict-Transport-Security "max-age=15768000;includeSubDomains" 
env=HTTPS

</IfModule>

 

How can I tell Apache to not set HSTS for specific virtual hosts (using some 
type of IF statement) using one global directive (instead of unsetting inside 
the specific vhost’s conf)?

 

Thanks
