Using data from capture request header Host

[Jose Luis Gordo Romero]

Hi,

First congrats for this great software!

I'm forcing https in haproxy (https requests come from stunnel):

        #################
        # Rewrite Rules
        #################
        # Set acl first
        acl secure src 127.0.0.1

        redirect prefix https://www.domain.com if !secure

But I have multiple subdomains (not fixed) client1.domain.com,
client2.domain.com, client-n.domain.com... and for the redirect to https I
need to get and pass the host header.

I see that haproxy can capture the host

capture request header Host len 15

But only for logging? I need use the Host header to redirect

redirect prefix https://{HOST} if !secure

Is possible?

Many thans in advance
Jose Luis
