Killing sessions on another server

[dd3123]

I've been PHPing for a while now, but never had to do this before, so I'm wondering if this is one of those rare n00b issues I've just never run into.

Basically I've got set of pages at say http://www.mypages.com/blahblah

after a bit, users go to a secure server at

https://secure.mypages.com/blahblahblah which starts a new session and tracks various things.

Now then, at some point I want the user's session & variables at
http://www.mypages.com/blahblah to be automatically destroyed while still at https://secure.mypages.com/blahblahblah

How might I do this without using header() to forward them to the nonsecure area and then destroying the session?

I've never had to do this BUT here is goes...

Get the session id for the HTTP server
use

session_id();

pass it to the HTTPS server via URL or Hidden Form Input
when you want to kill the old session call a php script on the HTTP server that will accept the session id and set it with the session_id() function.

Start the session and then destroy it.
