[squid-users] Unsupported method in request dropbox.com

Hi everybody!!

I get these messages on cache.log:

2011/06/14 10:23:54| clientParseRequestMethod: Unsupported method
attempted by client_ip: This is not a bug. see squid.conf
extension_methods
2011/06/14 10:23:54| clientParseRequestMethod: Unsupported method in
request 'X-Dropbox-Locale: es____'
2011/06/14 10:23:54| clientProcessRequest: Invalid Request

when accessing dropbox:

client_ip - user_name [14/Jun/2011:10:23:54 +0200] "GET
http://notify3.dropbox.com/subscribe? HTTP/1.1" 200 366
TCP_MISS:DEFAULT_PARENT

doing a tcpdump on squid eth and filtering by client ip address I obtain this:

I don't understand why it says unsupported method when it is just a
GET. Can anyone help me?
I use Version 3.0.STABLE25

thanks a lot!
