2982487 - "A request for server & was sent to server" message when accessing with SAP Web Dispatcher

Symptom

When executing a url, "500 Internal Server Error" is shown in the browser when the session has been inactive for a period smaller that the keepalive timeout idefined in parameter
  "icm/server_port_<nr> = PROT=HTTPS,PORT=<nr>,TIMEOUT=<nr>,PROCTIMEOUT=<nr>"

 The correspondent application shows "A request for server & was sent to server" error message.

 Executing the same application without SAP Web dispatcher works fine.

 In the SAP Web dispatcher trace file (dev_webdisp), level 2 the following entries appear:

[Thr <nr>] HTR: found stack ABAP for URL <application url>
[Thr <nr>] HTR: routing destination type = ICF/ABAP .
[Thr <nr>] HTR: found esid <external session id>-
..
[Thr <nr>] IcrITabPurgeEntry(1): entry removed after timeout (idle time=<nr>, context timeout=3600)
...
[Thr <nr>] HTR: No server name found in session table; group !DIAG*, <external session id>
[Thr <nr>] HTR: ESID backup cookie detected! Applying backup for <external session id>.
[Thr <nr>] IcrSessionTabApplyBackup: Applying ESID backup <external session backup id>"
..
[Thr <nr>] IcrSessionTabApplyBackup: ESID backup <external session backup id> will be ignored, because context timeout reached!
