+ * Creates a http form including an embedded {@code InfoBoxReadRequest} for reading the identity link.<p/>
+ * In detail:

+ * <li>Renames the moa session id.</li>
+ * <li>Removes ExecutionContext property {@linkplain at.gv.egovernment.moa.id.auth.MOAIDAuthConstants#PARAM_SESSIONID PARAM_SESSIONID}.</li>
+ * <li>Creates the http form mentioned above.</li>
+ * <li>Returns the http form via HttpServletResponse.</li>

+ * Expects:
+ * <ul>
+ * <li>HttpServletRequest parameter {@linkplain at.gv.egovernment.moa.id.auth.MOAIDAuthConstants#PARAM_SESSIONID PARAM_SESSIONID} <strong>or</strong></li>
+ * <li>ExecutionContext property {@linkplain at.gv.egovernment.moa.id.auth.MOAIDAuthConstants#PARAM_SESSIONID PARAM_SESSIONID} (in case of legacy authentication without CCE selection, where the moa session is not provided by request parameter).</li>

+ * Result:

+ * Possible branches:
+ * <ul>
+ * <li>In case of STORK authentication
+ * <ul>
