I am trying to determine the rules of engagement when you use an ESRI REST service
I issue the following request
It normally returns statuscode of 200 and a json string containing a polygon
every now and again (perhaps 1 in a 1000, 1 in 1000000) it returns the following
HTTP/1.1 200 OK Strict-Transport-Security: max-age=31536000;includeSubDomains Vary: Accept-Encoding Cache-Control: private,no-store,no-cache Content-Type: text/html; charset=utf-8 Date: Sun, 30 Jun 2019 11:00:21 GMT Server: Microsoft-IIS/10.0 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Set-Cookie: ZNPCQ003-32383000=6f2aa75d; Path=/; Domain=.dmp.wa.gov.au; HttpOnly Via: 1.1 gissdi.dmp.wa.gov.au (Access Gateway-ag-683BD5D4662193FD-9926260) Content-Length: 7293
Could not access any server machines. Please contact your system administrator.
Leaving aside the obvious error that has occurred somewhere between the ArcGIS WebAdapter and the server machine. (although any clues would be appreciated!)
The answers to these questions go the heart of how code should check the response from a REST call
My expectation was that a code of 200 says that the request has been accepted and processed and that the result of that processing (including possible errors) is contained in a json construct.
