DR-Web allows the use of Web browsers to access management information in SNMP agents. Agent products based on DR-Web accept HTTP requests in addition to SNMP requests for information. Manager products based on DR-Web accept HTTP requests, initiate SNMP requests to retrieve the desired information, and repackage the SNMP responses as HTML to return to the Web browser. The DR-Web interface is essentially the same for all DR-Web entities, both agents and managers.
DR-Web is designed to allow safe, controlled access to managed information. The Web server is built into the Master Agent for added security. HTTP and SNMP requests for information are handled in the same way. After an SNMP message or an HTTP message has been deciphered, the essentials of the request are inserted into EMANATE’s internal queuing subsystem. From there, information is retrieved in the "normal" way from EMANATE Subagents. Afterwards, a response message (of the appropriate type) is created and sent back to the sender of the original message.
