When executing a url, "500 Internal Server Error" is shown in the browser when the session has been inactive for a period longer than the SAP Web Dispatcher HTTP session timeout "wdisp/HTTP/context_timeout" (Default value 3600 seconds)
This can happen, for example, when using an application in the morning without closing the browser the previous day.
The Web Dynpro application shows "A request for server & was sent to server" error message
Executing the same application without SAP Web dispatcher works fine.
Also, after closing and re-started the browser. the error does not occur, as long as wdisp/HTTP/context_timeout is not exceeded.
In the SAP Web dispatcher trace file (dev_webdisp), level 2 the following entries appear:
Internal server errror, timeout , KBA , BC-CST-WDP , Web Dispatcher , BC-WD-ABA , Web Dynpro ABAP , Problem
