This patterns gives tips on using SafeURL with encryption in Stream Rules . Also when you should use Thread vs Requestor.

EncryptionPattern3.jsp

/* Note that this is for Stream rules */
/* Below snippet is a JS function in a control performing a server call */
/* Important Tip 
      Use encryption when you already have code using :
httpRequestAsync 
pega.util.Connect.asyncRequest 
openWorkByURL
openURLInWindow
*/ 
<script>
function bulkProcess(ListName, flowAction, id,classname, skipActionCheck)
{
	if (classname == null || classname == "All Classes" )
		classname = ""; 

	 var encodedID = encodeURIComponent(id);
	 var oSafeURL = new SafeURL();
         oSafeURL.put('pyActivity', "Assign-.BulkProcessAssignments" );
         oSafeURL.put('ListName', ListName);
         oSafeURL.put('TaskStatus', flowAction );
         oSafeURL.put('ID', encodedID);
         oSafeURL.put('moreBulkProcessing', "false");
         oSafeURL.put('ClassName', classname);
         oSafeURL.put('skipActionCheck',skipActionCheck);
         openWorkByURL(oSafeURL);
}

/* The solution is you can encrypt the url string pyActivity=XXX and pass the encrypted string to SafeURL */

function bulkProcess(ListName, flowAction, id,classname, skipActionCheck)
{
	if (classname == null || classname == "All Classes" )
		classname = ""; 

	var encodedID = encodeURIComponent(id);
	/* Note how we are using Requestor , as second argument . OpenWorkByURL action is a cross thread action */
	var oSafeURL = new SafeURL("<%=pega_rules_utilities.pzEncryptURLActionString(tools, "Requestor","pyActivity=Assign-.BulkProcessAssignments")%>");
         oSafeURL.put('ListName', ListName);
         oSafeURL.put('TaskStatus', flowAction );
         oSafeURL.put('ID', encodedID);
         oSafeURL.put('moreBulkProcessing', "false");
         oSafeURL.put('ClassName', classname);
         oSafeURL.put('skipActionCheck',skipActionCheck);
         openWorkByURL(oSafeURL);

}

  /* You can also use SafeURL_createFromURL with encrypted URL as argument */
  
var oSafeURL =  SafeURL_createFromURL("<%=pega_rules_utilities.pzEncryptURLActionString(tools, "Requestor","pyActivity=Assign-.BulkProcessAssignments")%>");
