I've read that sessions in the url are a big problem with search engines.
I don't know why, but when a session starts the session id appears in the URL (and I've noticed that only on DreamHost).
I've managed to get rid of this using this line of code:
Now, the links on my page look ok (without the session id) but the search engine (Google) still indexes my pages including that annoying session id.
Is there another way to solve this problem?
