Universal Login Help

I am building a universal login for our site CaribbeanChoice.com and want to make sure that I am doing this right.

I have included common.asp as an include on all pages where I placed the Universal Login. 

Am I correct that I have to include the following code somewhere at the bottom of the page?

<%
 'Clean up
 Set rsCommon = Nothing
 adoCon.Close
 Set adoCon = Nothing
%>

I have created a common-disconnect.asp file that contains this and included it at the bottom of all the pages that I included the common.asp include.

Is this correct?  Is there anything else I need to include or need to know about?

Also, some other scripts use a different connection string, and that is also included as an include at the beginning of the page.  I haven't had any problems so far, but is it okay to have 2 connection strings on the same page to the same SQL database (but accessing different tables in the same SQL database)? 

Thanks.

make sure you are also closing rsCommon, not just setting it to nothing.

rsCommon.close
