[drakma-devel] Changing content-type seems to have no effect

[Edi Weitz]

If you want to use the content type
"application/x-www-form-urlencoded", you can only use strings as
values in the parameter list.  You could, if you insist, read your
file into a string if it's not too big.  I have to say that this all
sounds wrong, though.

I have successfully uploaded to by drupal site using PHP Curl and in that code, I was only able to get it to work by using a content type of application/x-www-form-urlencoded (if I use a multipart/form-data request on my php page I get similar behavior to what I am now seeing with Drakma).  This is why I added the line :content-type "application/x-www-form-urlencoded"  to my second request (posted above) but it seems to have no effect.

Is there anyway that I can upload a file using Drakma using a content-type of application/x-www-form-urlencoded (I know this is not the recommended way of making this type of request but I think it may be the only way that my drupal site will accept the file).
