You need to check for a header named HTTPS_KEYSIZE or
HTTPS_SECRETSIZE, or on some servers HTTPS_SECRETSIZE. You'll only
see this header when you invoke the servlet through an SSL server. For
example, in one of my servlets, I have a line that looks like this:
int httpKeySize = request.getIntHeader("HTTPS_SECRETSIZE");
In general, for CGI scripting and servlet programming, I find it
useful to keep a script or servlet around that just loops through all
of the environment variables and/or headers and prints them. Then if
I need to check something, I just invoke that script or servlet and
see what gets sent. I have a similar one for testing HTML forms.
