HTTP Messages
Message | Cause / Solution |
|
|
HTTP/1.1 100 Continue | This indicates that the server and printer have begun |
| communicating and is often seen in place of HTTP/1.1 200 OK. |
|
|
HTTP/1.1 101 Switching Protocols | This indicates that the basic connection to the server worked |
| and the protocol is being switched to a more efficient protocol |
| for data transfer. |
|
|
HTTP/1.1 200 OK | This indicates that an HTTP GET or HTTP POST was successful. |
|
|
HTTP/1.1 30x Moved/Redirect/etc | This indicates that the URL specified has moved or that the |
| firewall redirected the printer to another location (typically this |
| is done to authenticate a user in a transparent proxy |
| configuration). |
|
|
HTTP/1.1 401 Unauthorized | This indicates that the printer either needs to authenticate with |
| the server or failed to authenticate with the remote server (or |
| server/router along the route to the server). |
|
|
HTTP/1.1 403 Forbidden | This typically means that the authentication was provided and |
| valid; however, the user does not have access to the requested |
| resource. |
|
|
HTTP/1.1 404 Not Found | This indicates that the remote URL provided points to an invalid |
| location on the server. This does indicate, however, that the |
| server name is valid. Just the path after the domain name is |
| invalid. |
