Can we expand the coverage of this ruleset to other hosts in *.unizg.hr?
See https://github.com/EFForg/https-everywhere/blob/master/CONTRIBUTING.md#enumerating-subdomains

We can, but we'll have to add them manually as not all of them support HTTPS properly.

I'll expand the ruleset next week with other hosts I'm aware of that support HTTPS.

@mrPjer Are you still interested in working on this pull request?

I'll update the pull request over the weekend with the additional rules.

It looks like there are a lot of subdomains for unizg.hr, which is common for a university. I suggest creating a PR with just ^, www, and maybe 10-30 other high-priority subdomains you want to cover, and add (partial) to the ruleset name. It will be difficult for you to get a PR approved with hundreds of subdomains, because huge PRs are very tedious to review.

I've expanded the ruleset to a few more hosts that I could find and verify that they work.

Please sort your domains in the order described in CONTRIBUTING.md#target-ordering. Also, please mention unizg.hr and www.unizg.hr in a top comment as described in CONTRIBUTING.md#non-working-hosts.

After you've done that, I'll take a closer look. There may be other things that need to be changed.

Updated. Let me know if there's anything else.

• Please use this instead, with filename Unizg.hr.xml :

<!--
	Invalid certificate:
		unizg.hr
		fer.unizg.hr

	Refused:
		www.unizg.hr

-->
<ruleset name="Unizg.hr (partial)">
	<target host="www.fer.unizg.hr" />

	<target host="ferko.fer.hr" />

	<target host="ffzg.unizg.hr" />
	<target host="www.ffzg.unizg.hr" />

	<!-- pmf.unizg.hr is not in DNS -->
	<target host="www.pmf.unizg.hr" />

	<!-- vef.unizg.hr is not in DNS -->
	<target host="www.vef.unizg.hr" />

	<target host="vojni.unizg.hr" />

	<rule from="^http:" to="https:" />
</ruleset>

and please let me know if you have any questions.

Thanks for the feedback! Updated per comment. Let me know if there's anything else I can improve.

That's it, thanks. Merged.
