How to do it

[experienced]

Hello,

There is one crawler Voila who is eating my bandwidth on daily or alternate days basis. I have already blocked the same in robot file ong time ago but still it is coming again n again, my stats shows

Voila 1832+89 207.73 MB 24 Mar 2010 - 10:12,

i have checked for voila correct agent name if i am using wrong name to block but i did not find anything.

Is there anybody who can help me stoping this voila, is it vola.fr or something else..

For the past few months I've been seeing the UA:

Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.8.1) VoilaBot BETA 1.2 ([e-mail])

I allow it on the simple string voilabot, which should do for blocking as well.

February there were 23,000 hits across a server of several dozen web sites. That's from a total of 145,000 hits from all permitted bots including google, yahoo, msn (the highest by far), vagabondo, yandex, ask, twiceler and a few others. It's about 12th on one of the more active sites (google is 4th).
