Java Servlet: how to escape the pound character when setting response header?

My Java servlet includes the following line:

response.addHeader("Content-Disposition", "filename=myFile.pdf");

I need to include a named destination defined in the PDF file as part of the file name. Ideally, I could use the following:

response.addHeader("Content-Disposition", "filename=myFile.pdf#Chapter3");

but when I run it, the url in the browser shows /path/to/myFile.pdf%23Chapter3 instead of the desired /path/to/myFile.pdf#Chapter3.

How to escape the # in "filename=myFile#Chapter3"? Escaping with \ gives a compile-time error. Escaping with &035; doesn't work either.

RFC 2616 defines that "the Content-Disposition response-header field has been proposed as a means for the origin server to suggest a default filename if the user requests that the content is saved to a file" so I don't think you can do what you intend to through your servlet. Maybe you will have better luck with some script in the pdf : you could imagine parsing its own name to dynamically set it at the right anchor at opening.
