HTTP Overview
The Hypertext Transfer Protocol (HTTP) is used for transferring web page information across the
Internet. It is an application-level protocol in the TCP/IP protocol suite. The connection-oriented
Transport Control Protocol (TCP) is adopted on the transport layer.
Currently, HTTP/1.0 is supported on the device.
How HTTP Works
In the HTTP, the client/server mode is used for communication. The client and the server exchange
messages following these procedures:
1) A TCP connection is created between the client and the server. Typically, the port number is 80.
2) The client sends a request to the server.
3) The server processes the request and sends back a response.
4) The TCP connection is closed.
Logging In to the Device Through HTTP
You can log onto the device using the HTTP protocol with HTTP service enabled, accessing and
controlling the device with Web-based network management.
To implement security management on the device, you can use the following methods to enhance the
security of the device.
z Enable HTTP service only when necessary.
z Change the port number of the HTTP service as a port number not commonly used (80 or 8080),
thus reducing attacks from illegal users on the HTTP service.
z Associate the HTTP service with an ACL to let pass only the filtered clients.
Protocols and Standards
RFC 1945: Hypertext Transfer Protocol – HTTP/1.0
Enabling the HTTP Service
The device can act as the HTTP server and the users can access and control the device through the
Web function only after the HTTP service is enabled.
