Official Docs: GlideServletRequest

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 GlideServletRequest API is used in processor scripts to access the HttpServletRequest object. The GlideServletRequest object provides a subset of the HttpServletRequest APIs. The methods are called using the global variable g_request. 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
