Hello, it seems that the code of your samples didn't work anymore in modern browser

loHeader = CREATEOBJECT("wwHTTPHeader")
loHeader.SetProtocol()
loHeader.SetContentType("application/pdf")
loHeader.AddHeader("Content-Length",TRANSFORM(LEN(lcPDF)))
loHeader.AddHeader("Accept-Ranges","bytes")
loHeader.AddHeader("Connection","Close")

Response.ContentTypeHeader(loHeader)
Response.Write(lcPDF)

Here is the result ( try with Firefox and Chrome )

Thank's for your help

Obsolete code from old docs... where is this from?

Don't use wwHttpHeader - all those properties and methods are on the Response object directly.

Tks for you reply

The link in the doc is https://webconnection.west-wind.com/docs/_0lc1chayy.htm

There is also a problem with your online demo We use this way for years but now it download the pdf rather than display it in the browser

PDF display depends on browser settings. You probably changed your default PDF viewer to something other than the Web Browser.
