The problem with the 3.0 update was that the "call" was a POST, which is disallowed on Apache, and yes, brought the Apache web server (all of it, not just the OO site) to its knees, instead of a GET for the update XML. So, based on this notice, it seems 3.1 might use a POST also? If so, there's nothing we can do vis a vis enacting this update for end users. >> Unfortunately, I can not provide any volume. > >> In the past more than 100 million download of OpenOffice.org package had > >> been counted by the OpenOffice.org community.
