Hi all, as formerly mentioned I try to return checked out files from a version management system with Zope. The check out is done within an external method (mthCheckout) that returns the binary data prepended by an appropriate header, eg. Content-Type: application/vnd.ms-excel Content-Disposition: inline; filename="mytable.xls" <binary data> BUT: When I call the external method within a document that only contains the following line: <dtml-call "mthCheckout(file)"> the user is prompted to choose what to do with the data. If open with Excel is chosen, Excel gets not only the binary data but also the header as its input. What shall I do to get the correct behaviour? What I want is that the appropriate application is called inside the browser filled with the binary data.
