Automatical download doesn't work if file is opened from a link

Hello,

I cannot download (save) a file when it is present on the screen as a link.

Example of the html code is: <a href="#" onclick="if(typeof jsfcljs == 'function'){jsfcljs(document.getElementById('opladenForm'),'opladenForm:bijlagenTable:29:j_id41,opladenForm:bijlagenTable:29:j_id41','');}return false">test.pdf</a>

If I click on this link in my sahi script, the popup 'Opening test.pdf' appears. I have the following lines in the .../apps/sahi/userdata/config/download_contenttypes.txt :

zip
excel
doc
application/vnd.ms
application/ms
application/octet-stream
text/plain
application/pdf
application/x-pdf
application/acrobat
applications/vnd.pdf
text/pdf
text/x-pdf

If I want to download a pdf file by clicking on a button that's on the same screen, the sahi automatical download function works! (Example: <input type="submit" value="Document" name="identificatieForm:j_id88"> => the *.pdf file is automatically downloaded by sahi).

I think this means my config is correct, but that there is a problem in sahi when a file download is started from a link? I use sahi v3.5 on Ubuntu 10.04 with firefox 3.6.13.

Can someone help me with this please?

Thank you in advance.

    Hi wgoris,

    It is possible that the two links return different content-types and so, only one of them works.

    Try this.
    1) With the Sahi proxy on, navigate to the screen where you have the download link.
    2) Stop the proxy (Leave the browser open)
    3) Open sahi/config/sahi.properties and change
    debug.traffic.log.unmodified=false
    to
    debug.traffic.log.unmodified=true
    4) Restart Sahi.
    5) Click on the download link.
    6) Once the pdf appears, stop the proxy, and change back to
    debug.traffic.log.unmodified=false
    (Otherwise the log folder will quickly fill your harddisk)
    7) Open sahi/userdata/log/traffic/ directory
    8) There must be a few folders created. Look for the one which best resembles your download link URL, and look at response.header_unmodified.txt
    9) Check for the Content-Type header and see whether it is different from the ones you have in download_contenttypes.txt. If not present, add it, restart Sahi, and check.

    Let us know what you find.

    Hello narayan,

    This is what I found in the logging:

    I added the line multipart/form-data to the download_contenttypes.txt file, but the problem still exists.

    Hey I am sorry, it should be

    response.header_unmodified.txt
    not
    request.header_unmodified.txt

    I am updating the above post to reflect that.

    Regards,

    Hi,

    There is no Content-Type header defined in the generated response.header_unmodified.txt file.

    That looks correct.

    Please open sahi/config/userdata.properties,
    and add

    download.download_if_contentdisposition_is_attachment=true

    at the end of it.

    Restart Sahi, and check if it works.
