Implementing SSL in WCF

Question

I have a small question about SSL implementation with Transport security in wcf.

What i understood from Research is,

• First client makes a request to WCF via https.
• Server will send a public key to client.
• Client uses this public key and encrypts the data and then sends across transoport.
• server receives the encrypted data and decrypts it using private key.

Is there anything wrong in my understanding......?

My second question is Whats the process when service sends the response back (how encryption and decryption occcurs?).

Thanks in advance

Note: My Question is not about how to implement SSL in WCF, it is how ssl workds both in case of request and response.
