Right... What are you expecting to happen? Is there something else going
on here? Some JaveScript or something on the page that's interfering
with the normal form submission process? Are you able to use
http://www2.research.att.com/sw/tools/wsp/ with your normal browser to
get a better idea of what's actually going on?

No, that's not right. I'm going to guess you used

warn "headers: $res->headers->as_string";

or something equivalent; that won't work since method calls aren't
interpolated. Try

warn "headers: " . $res->headers->as_string;

What sort of 'filename' are you expecting?

That looks correct for a POST from that form.

No. (Or, at any rate, not for a normal HTML form submission.)

Does the backend config.pl print the Content-Disposition header that
was suggested..?

Oh Yeah, that looks different:
headers: Connection:
close

GMT

Apache

But this doesn't really tell me anything either, does it?

Well I expected to see the filename that the browser would be
downloanding, that would be 'tropos.cfg'.

Ok, then that should work fine with my post string
'export_profile=Current%20Profile'.
Thanks for your help!

It says the the server is *not* returning the configuration file at all,
but it sending back the same HTML form you started with.

I'm going to take a wild guess and suggest that maybe the server
requires you to accept cookies properly. Try using WWW::Mechanize (with
a properly-configured cookie store) to run through the whole
login/download process.

OK. If you install the LiveHTTPHeaders FF extension, you should see that
when you perform a successful download the server sends a
Content-Disposition header. HTTP::Response->filename will pick this up,
if it's there.

Ah, hold on, with this extension I figured out that the correct post
string is:'export_profile=Current+Profile&save=Export' and with that i
see binary data coming back in $res->content - now i just wrote this
in a binary file and it seems to work.

Thank you for your help!
