sogo, httpd(8) and the rewrite need

[Joel Carnat]

Hi,

I was going to install SOGo on OpenBSD 5.7 using the native httpd(8).
In the readme, there are configuration examples for nginx and 
apache-httpd-openbsd. Nothing for the new httpd.
There are rewrite/redirect features that I can’t figure out how to setup with 
httpd(8).

nginx example:
    location = /principals/
    {
        rewrite ^ http://$server_name/SOGo/dav;
        allow all;
    }

apache-httpd-openbsd example:
RedirectMatch ^/principals/$ http://127.0.0.1:8800/SOGo/dav/

Is it possible to achieve such feature with httpd and/or relayd ?

Thanks.
