asp.net - stream pdf from MemoryStream -

-

i'm streaming pdf .ashx file browser using following code:

context.response.clear(); context.response.charset = ""; context.response.contenttype = "application/pdf"; context.response.addheader("content-disposition", "inline;filename=test.pdf"); context.response.addheader("content-length", stream.length.tostring()); stream.writeto(context.response.outputstream); context.response.flush(); context.response.end();

where context comes from:

public void processrequest(httpcontext context)

all works when using chrome or firefox , displays on browser. when use ie 11 blank screen. if go adobe reader->edit->preference->internet , uncheck "display pdf in browser" ie opens adobe reader , shows pdf properly. unchecked "display pdf in browser" shows blank screen:

if go ie "manage add-ons" shows adobe enabled:

i've seen other post nothing seems work. i'm thinking ie thing since chrome , firefox works , ie displays if don't have load on browser.

any ideas on causing this?
