HTTP:host in HTTP_RESPONSE

Hi Dan,

looking into the standard, Host seems to be a request header only, see

http://www.ietf.org/rfc/rfc2616.txt , e.g. p127 14.23

so this makes sense. Will double-check with a colleague, and then update the wiki

However, use the following to achieve your goal:

when HTTP_REQUEST {
    set my_host_header [HTTP::host]
}
when HTTP_RESPONSE {
    if { ( $my_host_header equals "example.com" ) and ( [HTTP::status] == 404 ) } {
        HTTP::redirect "http://example.com/error.jpg"
    }
}

Cheers,

Christian
