Google Maps - /* Guardian removed escaped content */

Last week, while i was loading Google Map in intranet web site, there was a syntax error in javascript loaded from http://maps.gstatic.com/intl/en_ALL/mapfiles/208a/maps2.api/main.js, and was not showing google map.
I found that firewall replaced some codes with "Guardian removed escaped content" text. I told our security deparment to unblock gstatic.com, i got rid of the problem. We use SmoothWall fire, it's latest updates were changed or configured to replace javascript comment with the text. Maybe this post can help someone who faced the same problem with me :)
