Hello,

I see that “Dual Certificate (RSA and ECC) support” is currently on the  
roadmap for nginx 1.9, but is not listed as in progress.

Is this feature guaranteed to be in 1.9? Will this feature allow us to  
serve a SHA-256 and SHA-1 cert at the same time?

Our platform is often used in developing countries that use J2ME phones  
and  
most only support SHA-1 certificates.

Thank you,  
Jon Emord

This patches are pretty stable (except you can’t use different OCSP  
responders for SHA1 and SHA256 certs and use different  
ssl\_stapling\_files).
