SSDPSearchResponse

org.cybergarage.upnp.ssdp.SSDPSearchResponse

public class SSDPSearchResponseextends SSDPResponse

Represents an SSDP search response message.

This class extends SSDPResponse to handle responses to M-SEARCH requests sent by UPnP control points. It provides specialized functionality for creating device discovery responses with appropriate headers and timing.

Key features:

Automatic OK status code setting
Cache-control header management
Server identification
EXT header for UPnP compliance
Default lease time configuration

This class is used by UPnP devices to respond to discovery searches from control points, providing standardized response format with required UPnP headers and device information to enable successful device discovery and connection establishment.
