Hi ! I'm trying to manage a flexible request_body_max_size based on the destination. I'm using SLES-10 (64 Bit) with squid 2.5.STABLE12. After reading some postings here, this should work, but it doesn't. Here is the external script and the squid.conf configuration. Thanks for help. /etc/squid/request_body_size.sh: #!/bin/sh while read line; do set -- $line length=$1 limit=$2 if [ -z "$length" ] || [ "$length" -le "$2" ]; then echo OK else echo ERR fi done /etc/squid/squid.conf (a part of it): external_acl_type request_body %{Content-Length} /etc/squid/request_body_size.sh acl request_max_20MB external request_body 20971520 acl upload dstdomain .example.domain.de http_access allow upload request_max_20MB request_body_max_size 2 MB Related postings: http://www.squid-cache.org/mail-archive/squid-users/200501/0078.html http://cvs.squid-cache.org/mail-archive/squid-users/200606/0377.html http://cvs.squid-cache.org/mail-archive/squid-users/200606/0409.html Regards, Markus
