[squid-users] Block file upload

Is it possible to stop people from uploading files using squid ie is there
some way to do an outbound mime type acl ?

I have added these two lines to my squid.conf :

acl fileupload req_mime_type -i ^multipart/form-data$
http_access deny fileupload

Here is my complete conf :

#===================================
cache_mem 32 MB
cache_mgr admin@gateway
cache_dir ufs /var/spool/squid 2000 16 256
cache_access_log /var/log/squid/access.log

cache_store_log /var/log/squid/store.log

But it not works ! Has anyone used this acl before and has a sample from
the conf file ?
