I am attempting to use client certificates as the authentication
mechanism over an SSL connection.  

The server (Tomcat 5.5) is configured to require all connections be
accompanied with a valid client certificate.  As far as the browser
and server are concerned, this works fine.  The mxml file is requested
by the browser, the server challenges the browser for a client
certificate, which it receives, and the mxml file is retrieved and
displayed correctly.  So far, so good.

The problem is that any subsequent HTTPS requests from the flex client
(NOTE: the flex client, NOT the browser) do not contain the client
certificate.  

The 'http-service-proxy-debug' log states:
 
07/11 17:09:04 ERROR %%500%%Software caused connection abort: recv
failed
07/11 17:09:04 ERROR -- GET status: 500, target:
https://localhost:8443/mtx-dx-test/GetUserRoles.do
?includeRoles=manager&excludeRoles=

Setting the JVM option '-Djavax.net.debug=ssl:handshake', std out
states:

*** CertificateRequest

Relaxing the server configuration to not require client certificates
fixes the problem, so it appears fairly clear that the client
certificate is not being managed correctly by flex.

Is there an flex-config.xml option I am missing?  Is this a supported
configuration?

Thanks in advance.
