a very nice regex tester for you:
http://www.roblocher.com/technotes/regexp.aspx
you can try there and move on to squid.

http_access deny rutube rutube_Files
But there is still question - how cut off .iflv instead of cutting player.swf?

Impossible? Looks very possible from that snippet you give below...
Rutube.ru uses inframe incapsulation of video via java-script. Example:
http://rutube.ru/tracks/4567054.html
piece of code:
<script type="text/javascript">
var rt_referer = escape(location.href); playMovie('pid',
'http://rutube.ru/player.swf?buffer_first=1.0&file=http%3A%2F%2Fbl.rutube.ru%2Fdb9decb3ae2341724c72e6490b028cfd.iflv&xurl=http%3A%2F%2Frutube.ru%2Ftrackinfo%2Fdb9decb3ae2341724c72e6490b028cfd.html%3Fad_ids%3D&image=http%3A%2F%2Ftub.rutube.ru%2Fthumbs%2Fdb%2F9d%2Fdb9decb3ae2341724c72e6490b028cfd-1.jpg&&autoload=true&fsb=true&logo=false&newWnd=false&rAngle=0&uid=3692805&referer='
+ rt_referer);
</script>
So it freely passes through rep_mime_type, rep_header, url_regex ().
The first two yes possibly. But regex can catch anything, that is both its
benefit and part of the price. If you are not catching it with regex then
your regex rule is wrong.
A urlpath_regex for "^/player\.swf" can catch these videos when paired with
a dstdomain ACL for rutube.ru.
Please, give me solution how Squid and/or SquidGuard could cut off
video, not disabling access to site itself. Approach is to deny video
content, not site itself.
NB Using rep_mime_type, rep_header, url_regex works fine with
youtube.com - it lets to download shockwave player, but player is
unable to download and play video.
rutube.ru is not youtube.com. They have different owners, different authors,
and different URL patterns. Expecting them to behave exactly the same?
