I have 2 different domains with their respective certificates, but both are hosted on one single IP. problem is that when i enable one, then the SSL certificate is enabled for both sites. like SSL for site A is applied to site A and B as well. but if i disable the certificate of site A, then the SSL of site B remains on the site B and works properly. how to resolve this issue.

i have enabled name based virtual hosting and tried many tweaks, noting works so far.

You'll need to post the relevant parts of your configuration, I think. – Michael Hampton Feb 4 '13 at 20:03

Name based virtual hosting doesn't work for SSL, as the Host header is part of the encrypted payload - Apache doesn't know which certificate to present.

You need a second IP for the second certificate.

Or you need to get a single certificate that covers both names. – David Schwartz Feb 4 '13 at 20:02
You've never heard of SNI? – Michael Hampton Feb 4 '13 at 20:02
@MichaelHampton: SNI is really not a solution yet since there are still too many browsers out there that don't support it. – David Schwartz Feb 4 '13 at 20:03
@MichaelHampton I have, and unfortunately it's a no-go in most environments because of IE+XP. – ceejayoz Feb 4 '13 at 20:03
Ehh, 15% and dropping may or may not be "too many" depending on many factors. – Michael Hampton Feb 4 '13 at 20:04

You need a dedicated IP address per SSL certificate. That is a requirement.

You need a SAN/UCC cert which allows multiple domains on 1 ip address. I've had your configuration before on an Amazon AWS instance and at the time they only allocated 1 ip address per server. I still have 5 sites with different domain names using a single Subject Alternative Name cert on that server.
