Agreed, Iooked at this when creating a failover service, and trying to replicate all the TCP and TLS data ended up using significant CPU processing and network bandwidth that it wasn’t worth it; in addition to intrusive OpenSSL changes.
You should try to have a way to detect and re-establish a failed connection; it’s significantly easier to do, and requires no modification of the OpenSSL code. Alternatively, having two simultaneous connections might work out. -- -Todd Short // tsh...@akamai.com<mailto:tsh...@akamai.com> // "One if by land, two if by sea, three if by the Internet."

No. This is not currently possible, and is unlikely to ever happen in OpenSSL. It’s too hard. -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
