Re: [squid-users] deny downloads

Hi all,

I am forwarding my previous message to the news group again. Because nobody
responded to my email.

I want to block users downloading
any gzip or zip files using their browser. I have the following in my squid.conf
file:

acl Downloads urlpath_regex \.gz$ \.GZ$ \.zip$ \.ZIP$ \.arj$ \.ARJ$ \
.lha$ \.LHA$ \.tgz$ \.TGZ$ \.gzip$ \.GZIP$ \.exe$ \.EXE$

http_access deny Downloads !POST

But it still allows me to download.

Thanks,
Rajesh.
