Provide tab title with reportlab generated pdf

Question

This question is really simple, but I can't find any data on it. When I generate a pdf with reportlab, passing the httpresponse as a file, browsers that are configured to show files display the pdf correctly. However, the title of the tab remains "(Anonymous) 127.0.0.1/whatnot", which is kinda ugly for the user.

Since most sites are able to somehow display an appropiate title, I think it's doable... Is there some sort of title parameter that I can pass to the pdf? Or some header for the response? This is my code:

def render_pdf_report(self, context, file_name):
    response = HttpResponse(content_type='application/pdf')
    response['Content-Disposition'] = 'filename="{}"'.format(file_name)

    document = BaseDocTemplate(response, **self.get_create_document_kwargs())
    #  pdf generation code
    document.build(story)
    return response

Seems that Google Chrome doesn't display the PDF titles at all. I tested the link in your comment (biblioteca.org.ar) and it displays in Firefox as " - 211756.pdf", seems there's an empty title and Firefox then just displays the filename instead of the full URL path.

I reproduced the same behaviour using this piece of code:

from reportlab.pdfgen import canvas

c = canvas.Canvas("hello.pdf")
c.setTitle("hello stackoverflow")
c.drawString(100, 750, "Welcome to Reportlab!")
c.save()

Opening it in Firefox yields the needed result:

I found out about setTitle in ReportLab's User Guide. It has it listed on page 16. :)
