I am trying to do the same thing. Did not yet figure out how. If you view the
source of the NCBI page than you will see that things like sequences are
uploaded via the POST method. So you need to specify all the POST items in the
headers. (I think). If you look in the archives of : comp.lang.perl under the
keyword "POST" than you will find a lot of scripts that will do that or similar
things. The scripts become complicated because of synchronisation problems. So I
find it difficult to figure out how to use the examples . I am now looking for a
site which will do the same but with a simpeler interface  :(   Please let me
know if you have other ideas.

The error is caused by an empty POST parameter (I think ?)
