Applicable in all events.

Example

when HTTP_REQUEST {
    url_list = {"/admin", "/api", "/private", "/secure"}
    url = HTTP:uri_get()
    status, count, t = class_match(url, "starts_with", url_list)  
    debug("status %s, count %s\n", status, count)   
    -- Safe iteration with type checking
    if type(t) == "table" then
        for k, v in pairs(t) do
            debug("index %s, value %s\n", k, v)
        end
    else
        debug("ERROR: Expected table but got: %s\n", type(t))
    end
}

This command returns three parameters:

• status: a boolean indicating whether at least one match was found (true) or not (false).

• count: an integer representing how many matches were found in the list.

• t: a table containing the matched indexes and their corresponding values.
