405 - Method Not Supported
The client attempted to request a resource using a request method not supported
by either that resource or Savant. Some client programs (such as Netscape's
roaming access applications and some of Microsoft's web-enabled applications)
use proprietary request methods that are only supported by proprietary servers.
Savant strictly supports the official HTTP 0.9, 1.0, and 1.1 protocols and does
not support these proprietary request methods.
