wondering if the contents of web.config is already loaded into cache, and 
if there is any benefit loading data from web.config into cache variables? 
faster access?.

i.e. web.config
<add key="ConnectionString" value="SERVER=abc; DATABASE=xyz; UID=sa; 
PWD=;" />
<add key="OtherImportantInfo" value="some value" />

1. access directly from config file in an aspx page
string connection = System.Configuration.ConfigurationSettings.AppSettings 
["ConnectionString"];

2. or load into cache during Application_Start in global.asax
Context.Cache ["ConnectionString"] = 
System.Configuration.ConfigurationSettings.AppSettings 
["ConnectionString"];

then in aspx page
string connection = Cache["ConnectionString"].ToString ()

is there any performance benefit to #2 ?

any feedback would be appreciated.
