Hi,... i have this in my squid.conf for a initial welcome page: external_acl_type session ttl=300 negative_ttl=0 children=1 concurrency=200 %SRC /usr/local/bin/squid_session -t 300 acl session external session http_access deny !localwebsrv !windowsupdate !session deny_info http://www.invalid.invalid/session.html?url=%s session It works, as it should. (The low ttl's are only for testing, and the .html is actually a php page.) Now i want to have the customers to check a html checkbox and press a button on this page first, before the session is started. How can i archive this? The behind for this is, that for the german law a simple submit button is not enough. best regards Stefan --
