I have notice today another two problems with the POST method.
1. It seems that the the onreadystatechange function isn't being
called most of the time.
2. I tried to change the request header "Connection" from "keep-alive"
to "close" and it seems to ignore my attemt.

Using jQuery solve the first problem tough.
