Hi Don,

The headers you listed should be sufficient. This is how returning a PDF file works in AFP:

<%
  * generate the PDF file and read it into lcPDF
  * FILETOSTR() is just an example
  lcPDF = FILETOSTR(JUSTPATH(FILE.GetLocation())+"\Sample.PDF")

  * Display the PDF file in the browser
  Response.ContentType = "application/pdf"
  Response.AddHeader( "Content-Disposition", "inline" )
  Response.BinaryWrite(m.lcPDF)
  

Make sure the Content-Length header is exactly the size of the PDF file and you don't send anything else to the browser.
