Problems with appcache

Every time I’ve tried to use appcache I’ve had problems and there are posts over the forums with different issues that arise. Things like the page infinitely refreshing.

Here are two for example:

All I’d really like to do is cache about 20 images in local storage. Is there an easy way to do this with Meteor without auto caching everything?

Also, if I use the following in my nginx file, do I even need to use appcache?

        if ($uri != '/') {
            expires 30d;

I removed this for a while because some people were saying it was causing an Meteor to infinitely refresh.
