Unable to see decrypted client SSL requests

Hi folks;

I am using IE and|or Firefox to do some browsing to pages protected with SSL. I have the server private key, and have configured Wireshark to use it to decrypt the server responses. This works great. My problem is that the browser requests are still encrypted within wireshark so I am not seeing the entire ssl transaction in the clear.

Do I need to provide wireshark the private key being used my the browser for encryption ?? If so, where would I find the private key being used by the browser ??

Any help/guidance would be appreciated (yes, I have read the various wiki's but haven't seen this thoroughly addressed).

thanks, wk
