cumulative options in SQL query with Count function

I like to create one query which will produce cumulative result also

my query

select substring(access_time_, 0, 11) "Date", count(*)"Total Downloads"
from tab1  where iface_type='web_server' and access_time_ > 
'2004-07-14 00:00:00.000' and access_time < '2004-07-29 23:59:59.999'and msisdn
not in (select number from excluded)
group by substring(access_time, 0, 11) order by  substring(access_time, 0, 11) asc

Above query will display following :

2004-07-20          2      
2004-07-27         6      

Now I would like to add cumulative result also : example
Date                    total          cumulative
2004-07-20          2                2
2004-07-27         6                8

is this possiable
