Apache HSTS exception for some virtual hosts

  • 772

In the global config section for Apache 2.2.15, I have the following (per recommendation)

<IfModule mod_headers.c>
Header add Strict-Transport-Security "max-age=15768000;includeSubDomains" env=HTTPS
</IfModule>

I would like to add this header only when the request is NOT for a specific host (dev.host.com). Which directive do I use to make header add occur only when not for a specific host?

PS: The second part of this question has been moved.

ssl

    1. If you only include the IfModule directive in a VirtualHost Directive for x.x.x.x:443, then it will only apply to that VirtualHost, and there only apply to the https protocol.

    2. You could try the directive

      <If "%{HTTP_HOST} = 'www.dev.domain.com'">
    <IfModule mod_headers.c>
        Header unset Strict-Transport-Security
        Header always set Strict-Transport-Security "max-age=0;includeSubDomains"
    </IfModule>
</If>

  2. In Apache 2.2 you can probably play with something like bellow.

    • Set an env to identify general case and exclude specific case:

      SetEnvIf HTTPS do_work_on_headers    
SetEnvIf Host "^www.myexcludedhostname.tld$" !do_work_on_headers

    • then conditionnally set headers:

      <IfModule mod_headers.c>
    Header add Strict-Transport-Security "max-age=15768000;includeSubDomains" env=do_work_on_headers
</IfModule>
