you should check for null before checking for .equals
eg:
if (password != null && password.equals("forgot"))
go to password forgot page (servletname?password=forgot)
if (user != null && user.equals("new"))
go to the new user sign in page (servlet?user=new)
That is because if the user does not fill in any information or
some such reason, the req will return null and java will throw
nullpointer exception if your string is null and you
exec .equals on it.
