[squid-users] welcome page with checkbox

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
