ThiyaguHi Mohamed, Thank you so much for your help. We are authneticating via mutual TLS and SN# of cert needs to extracted and pass it along in the HTTP header as X-Common-Name.
Thanks,Thiyagu.
ohh ,
so you need to extract this tls extension and insert it as a header to server side ?
you need to insert SNI as header " X-common-name "
Let me check for proper irule , I did before somthing like that , but it was another tls extension
