[racket] outgoing https requests with client certificate with plt 4.2.5

Has anyone ever used PLT Scheme 4.2.5 to do *outgoing* HTTPS requests 
*with client certificate authentication*?

Or used any Racket version for that?

(I ask because I am debugging what looks like a TLS handshaking problem 
at the moment, and having a sense of how tested the code paths I'm using 
might help direct my debugging efforts.)
