[users@httpd] Set header SSL_CLIENT_CERT

[Bernard]

​Hello,

I would like to ​set SSL_CLIENT_CERT header.
This is my situation :

Client -> Reverse-Proxy -> Apache

So, Apache is behind a reverse-proxy.
My reverse-proxy set a custom header (here we will use for the example the
header 'X-SSL-CLIENT-CERT').
And I would like Apache to be able to set the header 'SSL_CLIENT_CERT' with
the header 'X-SSL-CLIENT-CERT'.

But this configuration doesn't work :

<<
RequestHeader set SSL_CLIENT_CERT "%{X-SSL-CLIENT-CERT}s"
>>

How can I do that please ?
