Untouchable header fields ?

[Dirk-Willem van Gulik]

Folks,

Am I right in looking at (trunk, 2.2):

file: http_filters.c

    function basic_http_header
    ....
    if (proxy)
    ....
    else {
        date = apr_palloc(r->pool, APR_RFC822_DATE_LEN);
        ap_recent_rfc822_date(date, r->request_time);
        form_header_field(&h, "Date", date);
        form_header_field(&h, "Server", ap_get_server_banner());
    }

to surmise that modules or other dl-loaded code - fundamentally cannot
overwride certain headers such as the Date/Server ? Or is my module just
plain buggy ?

Thanks,

Dw.
