mobile users can be redirected to a non-existant www.m.project.org domain

Unsure if this is a new issue since switch from squid to varnish. Also, don't know who exactly to blame (varnish vcl or apache conf?)

btw, does happen with both HTTP and HTTPS.

Why DNS?

Domain related? Seemed better than general. Or Cunningham's Law? I dunno.

Confirming comment 0 (though I don't get the last two lines of output).

back to general. it's not dns. probably is varnish (VCL) but I haven't checked.

I think we've fixed this:
