Official Docs: GlideServletResponse

ServiceNow processors are equivalent to Java servlets. Processors provide a customizable URL endpoint that can execute arbitrary server-side Javascript code and produce output such as TEXT, JSON, or HTML. The GlideServletResponse API is used in processor scripts to access the HttpServletResponse object. The GlideServletResponse object provides a subset of the HttpServletResponse APIs. The methods are called using the global variable g_response. A useful global variable, g_target, is available in processor scripts. It contains the table name extracted from the URL. The URL to a processor has the format: https:///.do?= where the path endpoint and parameter endpoint are defined on the processor form
