Hai !!


yes it is restricted not to download those extensions in download.ban file

its downloading b'coz when u download through yahoo it is not really having .exe or whatever in the end or after the "."  , So to to block u can simply add words like  
exe mpeg dat ,
not \.mpeg$

Hope i m clear and try that .. inform us.

Hi Ricky,

Thanks for u reply, i have done this earlier like dat mpeg mp2 mp3 in the list, but as earlier told i am working for medical related company, in our clients side we mainly use google as a search engine we used to words like exercsies [which is related to exe]  datum [which is related to dat] to search like this millions of words,  if u put like this in google it will be access denied from squid proxy.

here is the problem i am facing ?? how to rectify and how to bypass this things.

if any suggestions/answers plz let me know.

Umm.. this is really a problem, I am not finding any way around. ..
Well in this case you can do one thing, use delay pool and slow down the download of those files, that way they will be available but not eating the bandwidth that way.
But for delay pools you will have to work on your own as these days I am very bad at delay pools and also is not having time to learn / understand them again. (though its in my list to work on soon).

Hi Dear
In file make entries like this
.exe$
.tar$
.gz$

After that it will block only sites that are ending with above words

This will help u

when he downloads file from mail etc as attachement then they don't really end with those extension !! and that is the problem !
