You might be better off with return container.index_html(context, 
context.REQUEST).

<dtml-if "REQUEST.SESSION.has_key('something')">
   <dtml-var "REQUEST.SESSION['something']">
</dtml-if>

In a Python script:

something = REQUEST.SESSION.get('something')
return something

In DTML:

<dtml-call "REQUEST.set('something', REQUEST.SESSION.get('something'))">

(Then refer to 'something' via <dtml-var something>)

It's not encrypted, you do need to use SSL..
