Forcing full ssl handshake

Hi guys,

 

I got serverside ssl working between F5 and two poolmembers. We have come across a requirement in which we need to have all ssl sessions to be negotiating via a full ssl handshake.

 

Does anyone know how I can make it do full ssl handshake for each and every session? Currently the F5 is doing a full ssl handshake at the start. Then resume handshakes are used for each and every session between F5 and pool member after the full handshake.

    Would the following do it for you:

     

    • Disable oneconnect;

       

    • Set cache size to 0 and enable "Strict Resume" in your SSL profile

       

    ?

     

    But your service will be crawling after this. :-)

    i doubt it will be crawling.

     

    you could also just close the SSL and TCP session from an irule at the point when it is needed.
