Hugo,

Are the "ImageReferer" configuration for virtual hosts below okay?

Currently using version 9.2

UrlToolkit {
    ToolkitID = domainone
    Header Referer .*\.domainone.com/.* Return
    Match .*(jpg|png|gif)$ Redirect http://www.domainone.com/nohotlink.jpg
}

UrlToolkit {
    ToolkitID = domaintwo
    Header Referer .*\.domaintwo.com/.* Return
    Match .*(jpg|png|gif)$ Redirect http://www.domaintwo.com/nohotlink.jpg
}

So on...

The rules are ok, but they can be bypassed. Just add a ?bla to the image URL and the filter won't work. I advice to place all images in a separate directory, for example 'images'. Change the pattern to match this directory.

UrlToolkit {
    ToolkitID = domaintwo
    Header Referer .*\.domain.com/.* Return
    Match ^/images/ Redirect /nohotlink.jpg
}

Question about the rule: 'Header Referer .*\.domain.com/.* Return'

Which one, that rule apply to: 'domain.com' or 'www.domain.com' or both?

*.domain.com applies to the rule. So, domain.com won't.
