Error Messages



Not Applicable


Steps to Reproduce



1. Retrieve a document from an external source and capture it in a byteArray as below,

//Get the byte array from the parameter page
byte[] byteArray=(byte[])tools.getParameterPage().getParameterValue("FileBinaryContent");
String fileName = (String) tools.getParameterPage().getParameterValue("FileName");
// create custom HTTP headers
HashStringMap aMap = new HashStringMap();
aMap.put("ContentDisposition", "inline;filename=\"" + fileName+ "\"");
aMap.put("ContentType", "application/force-download");
aMap.put("ContentType", "application/octet-stream");
aMap.put("ContentType", "application/download");
//Send the PDF File back to the user.
String result=tools.sendFile(byteArray,fileName,false,aMap,true);


2. Open the document from the Microsoft Edge browser. New empty requestors are created and noted in the SMA.


Root Cause



A third-party product issue. Edge browser makes a dual request to the server.


Resolution



Here’s the explanation for the reported behavior:

The Edge browser makes a dual request for an inline PDF. That is, the browser sends the first request after which the viewer initiates the second.
