I should add this may well be a bug in the Flash plugin but its not clear why 
it works OK in Mozilla and not Konqueror 

NPN_PostURL and NPN_PostURLNotify are still unimplemented in nspluginviewer. 
I'm currently working on this.

*** Bug 54201 has been marked as a duplicate of this bug. ***

Hi Till, any update on this? 

Subject: kdebase/nsplugins/viewer

CVS commit by staikos: 

Untested partial implementation of NPN_PostURL

I think it will do the post ok, but it won't return the results as it is
supposed to, and only http/https urls work.

I updated my plugin to flash 6 but I cannot get that demo to work.  It gives me a blank 
screen.  I don't see any debug output from it trying to call PostURL* either.  Are there 
other problems triggering this? 
 
It seems to work better in Netscape 4.x, but that also errors out with:

CVS commit by staikos: 

Make POST work in some cases.

See before and after on:
http://examples.macromedia.com/petmarket
(must have Flash 6)

This does not handle POST where the data gets returned anywhere except back to
the plugin.  That is, it doesn't allow the post results to appear in a browser
frame yet.  This is because I left:
// FIXME
there which of course doesn't do much.  It's all documented though.  Also
these functions only support "http" and "https" and nothing else.  I have no
personal intention to go any further with this, but I think it's supposed to
be possible to do other URLs too, at least that's what I figured from reading
the specs.

One other thing that does not work is plugins which put the POST data in a file
and pass the file name in to be POSTed.  I just haven't written the header
parser here.  If you find a site that uses it, show me, send beer/pizza, and
I'll do that for you too.
