Cor,

...

I am not exactly sure what you are referring to when speaking of
the SSL Session ID but AFAIU the information would be encrypted
(assuming the web server perform is running SSL) and not available
on the proxy.

It must be possible somehow, as our hardware based loadbalancers do
it as well.

I understand now that your load balancer is as well your SSL
accelerator. In that scenario, it makes sense. I may wait for NGINX to add the feature :) or just use Pound which
seems to have it as well (never noticed it was there before).

...

It's extremely easy in your case. Just grab a small plugin example
from SVN. Then change the hooks to login_after and login_failed.
As a source patch, add a hook for logout and call that hook in your
plugin as well. (but I wouldnt be surprised if a logout hook would
show up soon in SVN, as it seems really useful for other plugins).

Just read a bit here:

http://trac.roundcube.net/wiki/Doc_Plugins and here: http://trac.roundcube.net/wiki/Plugin_Hooks

Thanks, if I can do it without having to patch the code and use the
provided API - I will do so (when I have time) and just then post the
result. I can live with my patch for the time being.

I dont have a need for this plugin, and I really doubt many people
do. But you can do it, its not hard. We use Foundry hardware
loadbalancers, which I agree with Till is a better solution for this
problem. Then again, we may be a little bigger, so its easier to
justify the costs.

I know about them, they are not a bad product but the cost does not
justify a purchase for my usage when I can perform the same in
software without CAPEX atm. Citrix Netscaler AS 7000 are supposed to be good as well.

I will take from this discussion that you/the roundcube team are not
really interested in merging this patch. Could someone close the ticket in that case as I am not able to do it.

Thank you to everyone for your time in answering me and all the
information shared.
