+# Performance-Optimierung für Soap Aufrufe vom Server zum Server. 
+
+Dieser Patch fügt neue ILIAS-Setup-Optionen für die Webservices hinzu, um eine URL zu konfigurieren, die für SOAP-Aufrufe vom Server zum Server verwendet werden sollen.
+Siehe: https://gitlab.databay.de/ilias-hosting/ilias/-/issues/8
+
+## Patch-Markierungen
+
+Patches wurden mit `databay-patch: begin internal soap url` und `databay-patch: end internal soap url` markiert.
+
+## Änderungen
+
+Angepasst wurden im Rahmen der Funktionalität folgende Dateien:
+
+* Services/WebServices/SOAP/classes/class.ilSoapClient.php
+* Services/WebServices/classes/Setup/class.ilWebServicesConfigStoredObjective.php
+* Services/WebServices/classes/Setup/class.ilWebServicesSetupAgent.php
+* Services/WebServices/classes/Setup/class.ilWebServicesSetupConfig.php
+* webservice/soap/classes/class.ilNusoapUserAdministrationAdapter.php
+* webservice/soap/lib/nusoap.php
+* webservice/soap/server.php
+
+Folgende Optionen wurden für die config.json des ILIAS Setup hinzugefügt:
+
+```json
+{
+    ...
+    "webservices": {
+        ...
+        "soap_internal_wsdl_path": "https://foo",
+        "soap_internal_wsdl_verify_peer": true,
+        "soap_internal_wsdl_verify_peer_name": true,
+        "soap_internal_wsdl_allow_self_signed": false
+    }
+}
+```
+
+Die Optionen:
+
+* `soap_internal_wsdl_verify_peer`
+* `soap_internal_wsdl_verify_peer_name`
+* `soap_internal_wsdl_allow_self_signed`
+
+setzen die entsprechenden SSL Optionen wenn `soap_internal_wsdl_path` gesetzt ist (Siehe: https://www.php.net/manual/en/function.stream-context-create.php).
+
+## Spezifikation
+
+Der Patch setzt folgenden FR um: https://docu.ilias.de/go/wiki/wpage_8363_1357
