First a little background infor that may help explain things...

We are a PROGRESS shop and are using their WebSpeed package. WebSpeed
provides us the ability to write programs as either augmented HTML or
as 4GL programs that output HTML (we use the former). Our development
system uses a CentOS 4.8 server for the database and CUI programs,
Windows PCs for GUI development and a Windows 200 Server for a web
sever and web development. The QA and live environments run on two
RHEL 5.4 servers, one for a database server & CUI program host and
one for a web server.

The WebSpeed programs run in CGI mode for both the IIS and Apache web
servers. Within our programs we can interrogate any of the standard
CGI and OS environment variables. On IIS I can get the HTTPS_KEYSIZE
value to determine the encryption key size but I have not been able
to find anything similar on Apache that will work. I had tried
SSL_CIPHER_ALGKEYSIZE in the past but it never returned a value and
now it appears the CompatEnvVars directive that was supposed to
generate this environment variable has been deprecated.

Here is a list of the CGI variables that I can see when using an HTTPS
connection:

SHLVL:  1

I hope that clarifies things a bit.

TIA
