This should work using the Category property as you later show in your
own post. This is a new feature of 1.2.11, though, the category is
fixed in 1.2.10 and earlier.

should work as well as
log4net.ThreadContext.Properties["Category"] = 500;

Not sure I follow you here.

You have likely swapped IsInfoEnabled and IsWarnEnabled (as you use Warn
if IsInfoEnabled and vice versa). Also note that IsWarnEnabled implies
IsInfoEnabled so you never hit that last branch.

You mean you want to switch the level on the type of exception raised?
Where is this code, inside Global.asax Application_Error method? Take a
look at Server.GetLastError and maybe unwrap (i.e. look at the
InnerException) if it is a HttpUnhandledException.
