How to download a stream

Hi,

my App's results should be downloaded as ASCII files. So I guess I
could create a file and link to it. (haven't tried that)

But I'd like to start a download from a stream. Otherwise I have to
take care about individual filenames and about deleting the files
after download.

So how to start a download and feed it a stream?

Thanks,

Hi Herbert,

A bit but hope not too late answer:

Returning an answer in a content type other that HTML is actually pretty
simple. Let me explain with example returning an XML:

1. make a new class, say XMLContent as subclass of WebElement
2. ovveride method #aidaContentType to return appropriate content type:

  XMLContent>>aidaContentType
    ^'text/xml'

3. MyApp>>viewAsXml
  | xml |
  xml := '<xml>some XML content</xml>.
  e := XMLContent new.
  e addText: xml.
  ^e

4.in browser open something like:

        http://localhost:8888/myobject?view=asXml

To explain a bit: if App view method return an element with content type
different than default, this content type will be set in a header of
response to your web request. This way we can very simply return content
in any content type we like, like XML, CVS, JPG etc.

I put this explanation on our website in FAQ too:

Hi Janko,

thanks, it helped. And I found the class comment of WebNonHTMLResource
which explained why my downloads still started with a html extension.


Cheers,
