Here is a quiz that will trow up a few comments.

What are the benifits of an seo mod that would stop PHP sessions being generated if the user agent of the visitor is detected to be a search engine.

What I suppose I mean in is that without this mod the search engines will see URLs as http://www.domain.com/index.php?act=...23r456tg873gg5. mmm, not very nice is it?

So your thoughts on this and whether it is worth doing this in my modification?
