f$WebService

Execute a web service that can be called with the REST protocol. Details for this in Wikipedia https://en.wikipedia.org/wiki/Representational_state_transfer Usually data is given to the web service in the form of an XML buffer. The result is returned similarly as an XML buffer and optionally in an XML-file if declared in PGOutput. In order to display the text correctly the encoding (key word ’Accept-Charset’) should be defined in the PGOutput (HeaderIn). Possible values for Accept-Charset are: ’ISO-8859-1’, ’UTF-8’, ’UTF-16’.
