using request_body_max_size with acl

["ankush grover" <ankushsquid@xxxxxxxxx>]

hey friends,

I am trying to use request_body_max_size with acl. I have different
groups which need different upload and download limits. I am able to
configure squid for download limits.

I found a script for request_body_max_size which can be used inside an
acl  script is not working with the acl.

Script is below
#!/bin/sh
while read line; do
 set -- $line
 length="$1"
 limit="$2"
 if [ "$length" -le "$2" ]; then
    echo OK
 else
    echo ERR
 fi
done


external_acl_type request_body %{Content-Length} /etc/squid/read.sh

acl request_max_20MB external request_body 20971520


acl defined in the squid.conf

acl download  src 192.168.1.15

http_access allow  download request_max_20MB


request_body_max_size  0 KB   (parameter as defined in the squid.conf)

Is there any other script which can be used inside the acl for
request_body_max_size ?

I am using squid 2.5 stable 6 on FC3.

Thanks & Regards
