The trouble causing HTTP POST requests found in the server logs does not seem to 
be related to the update function in former OOo versions.
I have investigated the update function HTTP requests from various former OOo 
versions in the server logs. All of them provide content for the HTTP UserAgent 
field. All of found HTTP POST request does not have such data.
Looking at some sample HTTP requests from one IP address reveals that the HTTP 
requests from the update function are unrelated to the HTTP POST requests.
I investigated the HTTP traffic of update function from former OOo versions (OOo 
2.2, OOo 2.3, OOo 2.3.1, OOo 2.4, OOo 3.x). None of these showed an HTTP POST 
I evaluated some server logs from days before the established redirects from 
INFRA-5112. Here, I could not found any of such HTTP POST requests.
My conclusion is that there were another function in OOo which causes these HTTP 
POST requests. OOo 3.2, OOo 3.2.1, OOo 3.3 does not seem to have such a 
function, because the redirects for their update functions had been established 
a couple of weeks ago and I did not found any HTTP POST requests.

In order to figure out what is going on here, I will follow up with Apache 
infrastructure. I will report on ooo-dev, when I know more.

Best regards, Oliver.
