| 101 | Switching Protocols | The requester has asked the server to switch protocols and the server has agreed to do so. |
| | | |
| | | The target protocol must be more advanced than the source protocol. |
| | | |
| | | For example, the current HTTP protocol is switched to a later version of HTTP. |
+-----------------------+---------------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
