```
    Description copied from interface: javax.servlet.http.PushBuilder
    
    Sets the URI path to be used for the push request. This must be called before every call to PushBuilder.push(). If the path includes a query string, the query string will be appended to the existing query string (if any) and no de-duplication will occur.
    
    Specified by:
    
    path in interface javax.servlet.http.PushBuilder
    
    Parameters:
