Adapter type: httpplugin. The HTTP Output adapter receives ad-hoc SQL queries in the form of HTTP POST requests from an HTTP client. The adapter sends these queries to the ESP Server, and publishes the result data to the HTTP client in XML format. This adapter can only be used to query ESP windows since it delivers a snapshot of the window content at the time of the query.
Install and configure your own HTTP client to use with this adapter. To configure this adapter in the ESP Studio, select the HTTP Output (external) adapter from the Palette.
