/* Google Code's messing up with requests, use HTTP/1.0 as suggested. More info:

http://code.google.com/p/support/issues/detail?id=6095
|

|
|
Of course it would be still too simple, coz IE will override settings, so
|
|
you have to disable HTTP/1.1 manually and globally. More info:
|
|
|
|
http://support.microsoft.com/kb/258425
|
|
|
|
So this code's basically useless since disabling HTTP/1.1 will work with the
|
|
above code too.
|

Update: a Connection: close header seems to disable chunked encoding.
