TLS pass through in apigee proxy

[dpatty]

Hi,

We are doing migration of API from CA Layer7 to Apigee. There are lots of API which running on mutual TLS for inbound request . As per migration plan we are going with approach of first brining apigee layer in front of CA Layer7 and route all traffic from apigee to Layer7 . 

Since apigee breaks TLS  in proxy endpoint before  routing the request to target there is  additional effort required to bind the certificate to target endpoint . Is this possible to make TLS pass through from apigee to Backend system (CA Layer7 here)

Thanks,

Patty
