Examples of javax.sip.header.ServerHeader

javax.sip.header.ServerHeader
The Server header field contains information about the software used by the UAS to handle the request. Revealing the specific software version of the server might allow the server to become more vulnerable to attacks against software that is known to contain security holes. Implementers SHOULD make the Server header field a configurable option. If the Response is being forwarded through a proxy, the proxy application must not modify the ServerHeaders. Instead, it should include a ViaHeader.
For Example:
Server: HomeServer v2 @see ViaHeader @see UserAgentHeader @author BEA Systems, NIST @version 1.2
