Hi Dave,
I think something like this should work:
when HTTP_REQUEST {
if {[HTTP::path] starts_with "/foldername"}{
HTTP::redirect "https://newsub.newdomain.org[string range [HTTP::uri] [string first "/" [HTTP::uri] 1] end]"
}
}
You can add debug logging to check the values for [string first "/" [HTTP::uri] 1] and [string range [HTTP::uri] [string first "/" [HTTP::uri] 1] end] to see how it works. The idea is that you get the first / after the first character in the URI and then read from that to the end of the original URI to determine the URI for the redirect.
