    • The GlideServletRequest API provides methods to use in processor scripts.

    ServiceNow processor scripts are equivalent to Java servlets. Processor scripts provide a customizable URL endpoint that can execute arbitrary server-side JavaScript code and produce output such as TEXT, JSON, or HTML. Use the GlideServletRequest API 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://<instance name.servicenow.com>/<path endpoint>.do?<parameter endpoint>=<value> where the path endpoint and parameter endpoint are defined on the processor form.
