Text Link to a catergory

[smart]

I have text after the log e.g.

 

Welcome back Name! Would you like to see which new products are available to purchase?

 

Then more text - saying Purchase from us XXX - Link To and Link To

 

these link go to a Catalogue link.

 

But when they go I loose the session.

 

And index.php?cPath=21&osCsid

 

The client has to log in again

 

Can this be done?

 

Thanks
