[sr-dev] Registrar module creates an extra branch

[Efelin Novak]

Hi Mino,

thank you very much. This solved the problem. Second lookup added (dunno
why) an extra branch. I assume this is a bug. Or do I have to specify second
lookup somehow special?

Now the question is: I needed second lookup just to make sure a user is not
online (the conditional redirect). Is it OK just to make query like this:

sql_query("ca","
           SELECT
                1
           FROM
                 location
           WHERE
                 username = $rU
","ra");

and check for the number of rows?

I find out that DB and memory content is not really the same. DB is
something about minute behind memory( Do you know the precise time?). If
this is true I'm ok with this time. Is there any other difference?

Thanks folks,

Efelin Novak
