Best form to restrict http method

Dear,

I don't think it's possible via a http profile.

But you can use an iRule or a LTM policy to restrict. Here is an example of the iRule:

when HTTP_REQUEST {
    switch [HTTP::method] {
        "GET" -
        "POST" -
        "HEAD" {
            return
        }
        default {
            HTTP::respond 403
        }
    }
}
