So far I can't get this to work. I have the following command line (in a script):

run_asciidoctor_pdf () {
	out_file=${1}.pdf

	# work out the options
	opts="-a current_year=$year \
		-a stylesdir=$stylesdir \
		-a resources_dir=$resources_dir \
		-a uml_export_dir=$uml_export_dir \
		-a pdf-style=$pdf_theme \
		-a pdf-stylesdir=$resources_dir \
		-a allow-uri-read -a cache-uri \
		-r asciidoctor-pdf -b pdf \
		--out-file=$out_file"

	# -a pdf-fontsdir=path/to/fonts 
	if [ "$pdf_trace" = true ]; then
		opts="${opts} --trace"
	fi

	asciidoctor ${opts} $2
	echo generated $(pwd)/$out_file
}

I just added the line '-a allow-uri-read -a cache-uri' to the previous version.

I installed open-uri-cached as above.

When I run my script, something happens, because I see this in /tmp (actually in cygwin's /tmp area):

/tmp
    /open-uri-1001
        /www.openehr.org   # this is indeed the site from which the image comes
            8a4608a543e26f1107b8842d250d74f7f86607db
            8a4608a543e26f1107b8842d250d74f7f86607db.meta

But there is no .png or .svg in /tmp. The source link is to a .svg.

The output from running asciidoctor, with trace turned on is:
