    when HTTP_REQUEST {
    set referer [ HTTP::header Referer ]
    if { [HTTP::query] != "" } {
        set RedirectUrl "https://test.domain.com/?__referrer=${referer}&[HTTP::query]"
    } else {
        set RedirectUrl "https://test.domain.com/?__referrer=${referer}"
    }
    HTTP::redirect $RedirectUrl
}

    This should do that for you - the typo in referer is your own

      Thank Pete,

       

      That is working now. Do you know if the referer header can do URL-encoding? Example:

      referer=https://www.google.com/my_good_stuff?q=foo&bar=baz should be referrer=https%3A%2F%2Fwww.google.com%2Fmy_good_stuff%3Fq%3Dfoo%26bar%3Dbaz

        You can use URI::encode with the set referer command which would be [ URI::encode [ HTTP::header Referer ]]
