Orphaned SQL Server Connections

 I am not sure if this is actually a sql connection I didn't dispose of.
The database the app use is franchise_search, login test

Here  are the results of sp_who before I start the web server and run the page

then I run the page and all I do is  
 
                    using (m_sqlConn = new SqlConnection(m_strSQLConnect))
                    {
                        m_sqlConn.Open();
                        //Log_History();
                        //FillCompany_DropDown();
                        //m_sqlConn.Open();
                        //BuildCategoies();
                    }
I open the connection never use it and return the using should close the connection.
But after I close the page sp_who add the line
56    0    sleeping                          test    HPDEV                                                                                                                               0        Franchise_Search    AWAITING COMMAND    0
Is this connection pooling or am I missing something?
No other app or anything can use the test connection  I just made it and changed the password.
