path
in interfacePushBuilder
- Parameters:
path
- Paths beginning with '/' are treated as absolute paths. All other paths are treated as relative to the context path of the request used to create this builder instance. The path may include a query string.- Returns:
- This builder instance
-
getPath
Description copied from interface:javax.servlet.http.PushBuilder
Obtain the path that will be used for the push request that will be generated by the next call topush()
.- Specified by:
getPath
in interfacePushBuilder
- Returns:
- The path value that will be associated with the next push request
-

getMethod
Description copied from interface:javax.servlet.http.PushBuilder
Obtain the name of the HTTP method that will be used for push requests generated by future calls topush()
.- Specified by:
getMethod
in interfacePushBuilder
- Returns:
- The HTTP method to be used for future push requests
-
queryString
Description copied from interface:javax.servlet.http.PushBuilder
Specifies the query string to use in subsequent push requests generated by a call toPushBuilder.push()
. This will be appended to any query string specified in the call toPushBuilder.path(String)

- the session ID generated in the originated request
null
- Specified by:
sessionId
in interfacePushBuilder
- Parameters:
sessionId
