Set-Cookie: _APP_session= path=/ HttpOnly My app returns a response with the following I submit a form to my web app and it responds with a PDF this works in all browsers except Edge where I get the "Something's keeping this PDF from opening" error. In IE 11, Firefox and Chrome - the PDF comes up as expected but in Edge (10030) I get a "Couldn't open PDF: Something's keeping this PDF from opening." page. (using webforms, after postback of a form to a new target) and then clears the response object, sets the response content type to application/pdf, adds a header for Content-Disposition with the name of the PDF (for Chrome to save the PDF with the correct name)Īnd the write out the byte array (BinaryWrite) to the response before closing. To follow up on this (and related to this issue: ), we develop a website that opens a new window but from the user's end, I see it on the user's end and as a developer for a web site. I know this is happening for others as well Right-click Start>Run and type gpedit.msc in the Run dialog box, and press Enter or click OK.Originally posted in the Windows Insider Program forums, I found a issue with opening PDFs using the latest version of the Edge browser (10130) and wanted to know if it has been addressed in later build of Edge.
