$r->headers_out->set('Server' => 'foo');
Greetings,
I'm trying to figure out where in the mod_perl innards I need to look to
map the accessor for the Server header.
I've changed core.c in httpd so that set_banner() is deactivated. This
results in a Server header of 'mod_perl/2.0.4-dev Perl/v5.8.8', so I
think that change is all that is needed to keep apache from overwriting
the header.
I don't see anything in xs/maps/apache2_structures.map so I figure that
I have to add server in there somehow?
Thanks in advance,
Fred

I was able to hack ap_add_version_component to dwim. So when I call
add_version_component() in perl now I can set the outgoing server header
to whatever I want. This hack is pretty lame but it took me all of a
few minutes to get working which was kind of nice. I suppose I could
make set_version_component call apr_pstrdup() instead of this hack.

you can call add_version_component() from perl, IIRC. but httpd will
always override the Server header, so the syntax in the subject will
never dwym.
