I have a site where I have Speedy set up for static caching. All is working smoothly, except for a page that uses query strings with Pro Form to generate the content. For example:

/page?child:custom_field=example

I would like to cache both the base /page and also the page with the results filtered by query string.

I see that there is a speedy_query_cache_allowlist config that should allow me to do just that. But I can’t seem to get that working.

The documentation doesn’t provide an example of what that config would look like, so it’s very possible that I’m just making a simple mistake in syntax. Here is what I have for the above example:

$config['speedy_query_cache_allowlist'] = ['child:custom_field'];

Should that work? Or do I need to construct that config differently?

Thanks!
