This allows sites using redirect=proxy to still generate ACME
certificates by not passing the acme requests through to the proxy.

We should also consider using this for other features available such as
own error documents, SSI and custom directives.

Avoid bashisms in the call to acme.sh

Closes #6326

See merge request ispconfig/ispconfig3!1595

This command is using features that are not POSIX-compliant (the [[ and
the || in them), that despite being supported by many shells (including
bash) are not available in dash.

Since system() runs the code with /bin/sh that is an interface defined
as only being POSIX-compliant, with no extensions, it should not presume
a specific shell in that.

There may be no guarantee that `$caller[...]` is actually set, or that
either `file` or `line` are not empty.

Marius Burkard authored 3 years ago and Gwyneth Llewelyn committed 3 years ago

Good point; I'd even use `!empty($caller['file']) && !empty($caller['line'])` to save a few cycles in the (improbable) case where both _may_ be set, but empty (thus making the whole exercise pointless...).
