[ic] ic 4.8.5 - session id in one-click searches

[interchange-users@icdevgroup.org (DB)]

Hi... I'm very close to opening my store. I want to avoid lost sessions 
for those who disable cookies. My questions is regarding one-click searches.

Is it wise to include
mv_session_id=[data session id]
in my search URL like this:

<A 
HREF="/cgi-bin/store/scan/ml=20/st=text/sf=prod_group/se=Stuff/mv_searchspec=Test/mv_session_id=[data 
session id]"Click</A>

instead of not including it like this:

<A 
HREF="/cgi-bin/store/scan/ml=20/st=text/sf=prod_group/se=Stuff/mv_searchspec=Test"Click</A>

And is there a two letter abbreviation for mv_session_id ? I saw none in 
the docs.
