ignore_query_strings with specified query parameters

[indykoning]

As mentioned in
statamic/cms#3111 (comment)
a useful feature would be to let static_caching.ignore_query_strings accept an array of query strings as well.

This could be used to filter the url parameters in https://github.com/statamic/cms/blob/6969fb6c54ce7f6630ae36d0d814aa6f4341c8d8/src/StaticCaching/ServiceProvider.php#L42

Why would this be useful?

Marketing tools love to throw useless url parameters into the mix, like:

• source
• ad_network
• utm_source
• utm_medium
• utm_campaign
• utm_id
• utm_term
• utm_content
• gad_source
• gad_campaignid
• gclid
• _gl
• gbraid
• amp
• __gads
• __atuv
• mpid

forcing Statamic to build these pages uncached, and creating cache files for a request that will only ever be used once.

This solution would leave the current nginx rules unable to resolve the file, but it would still be much faster and space efficient since it would be able to resolve the cache in PHP

I'm not sure if they've been documented yet, but have you seen statamic/cms#10701? It allows you to specify query parameters which'll be ignored when Statamic decides if a page already exists in the static cache.

I hadn't found it on the docs when I made this, I'll take a deeper look at it later and let you know.

Looking at the code this is exactly what I had in mind for this though!

Edit: there is indeed no documentation of this as of yet

[indykoning]

The feature is already implemented, even if not documented yet. So i can close this idea 🚀
