+1 512B sounds like an IPS/firewall is trying to do some MIME type pre-sniffing and determining that it isn't valid text/plain (note that is the MIME type served by mootools.net, I presume to facilitate downloading as an attachment as opposed to using the main site as your CDN). 1.2.0 (I don't know where exactly you are getting it from on mootools.net) may be getting served as application/x-javascript, since it is actively used to power the site + demos. This one may be sniffed according to different IPS rules. Another diff is that 1.2.1+ has a long hex build # at the beginning, which maybe is nonmatching with text/plain. Just a guess there. -- S.
