Subject Re: Using different SSL-connector settings for various Context

Hi.

Please don't top post here. Respond below the text to which you are responding.
It's easier to read that way. See below.

Sorry, as I mentioned earlier, I do not know much about SSL and cannot help you with the 
details.

One thing though : the setup of an SSL connection happens *before* Tomcat even knows to 
which application the browser wants to talk.  Some properties of that connection may not 
be changeable anymore, at the level of a Context.
You can just tell the Context to make use or not of some of these properties, not really 
change them.

In your case though, it seems that you want the following :
- clients connect via SSL
- some Context's then (later) require clientAuth
- and some other Context's (later) do not require clientAuth
That should be solvable just by the <auth-requirements> of each Context.

If you want some Context's to be accessible via HTTP/HTTPS, and others only via HTTPS, 
that also is a parameter that you can specify in each context's web.xml.
(<transport-guarantee> or something like that)
