Applying Multiple Certificates To Keystore

[RK <ra...@trafficpayment.com>]

Hi,
 
     I have a security certificate issued for my website for
<https://www.mydomain.com> https://www.mydomain.com . So if some one types
in  <https://mydomain.com/> https://mydomain.com an certificate mismatch
error is being displayed.
     So to avoid this problem I purchased a new certificate on the name of
<http://mydomain.com> http://mydomain.com  and applied to the same keystore
file but with a different alias name.
     But it doesn't' seem to work, is this a possible way of doing it or
this way it doesn't work.
 
     Can anyone suggest me an idea of how to get rid of this problem.
 
Thanks
