-- | Information about an HTTP method condition.
--
-- HTTP defines a set of request methods, also referred to as HTTP verbs.
-- For more information, see the
-- <https://www.iana.org/assignments/http-methods/http-methods.xhtml HTTP Method Registry>.
-- You can also define custom HTTP methods.
--
-- /See:/ 'newHttpRequestMethodConditionConfig' smart constructor.

    -- allowed characters are A-Z, hyphen (-), and underscore (_). The
    -- comparison is case sensitive. Wildcards are not supported; therefore,
    -- the method name must be an exact match.
    --
    -- If you specify multiple strings, the condition is satisfied if one of
    -- the strings matches the HTTP request method. We recommend that you route
    -- GET and HEAD requests in the same way, because the response to a HEAD
