sed cannot operate on literal strings so it's the wrong tool to use when you want to do just that, as in your case. awk can work with strings so just use that instead:

awk '
BEGIN { old="##END_ALL_VHOST##"; lgth=length(old) }
NR==FNR { new = (NR>1 ? new ORS : "") $0; next }
s = index($0,old) { $0 = substr($0,1,s-1) new substr($0,s+lgth) }
' "$SERVERROOT/conf/templates/$DOMAIN.conf" "$SERVERROOT/conf/httpd_config.conf"

You may need to swap the order of your 2 input files, it wasn't clear from your question.

Here's a way of doing it. Fancify the cat command as needed.

(pi51 591) $ echo "bar" > /tmp/foo.txt
(pi51 592) $ echo "alpha beta gamma" | sed "s/beta/$(cat /tmp/foo.txt)/"
alpha bar gamma
