@SupportedAll public class PAOSHeader extends Object
The PAOSHeader class is used by a web application on HTTP server side to parse a PAOS header in an HTTP request from the user agent side. This header is used by the User Agent as a PAOS server to publish which services are available, which PAOS versions are supported, etc.. An example PAOS header looks like the following:
 PAOS: ver="ver1","ver2",ext="ext1","ext2";"service1","opt11",
           "opt12";"service2","opt21","opt22"
 
This class has methods for obtaining all the parts inside such a header.
