Replacements for pages _headers and _redirects

Hi, I've just migrated from pages to workers for my remix/react router apps. I used the _headers and _redirects for forcing cache headers on all files under a directory, and removing trailing slashes. e.g. 
/favicon.ico?
  Cache-Control: public, max-age=3600, s-maxage=3600
/assets/*
  Cache-Control: public, max-age=31536000, immutable
/favicon.ico?
  Cache-Control: public, max-age=3600, s-maxage=3600
/assets/*
  Cache-Control: public, max-age=31536000, immutable
or 
/*/  /:splat  301 
/*/  /:splat  301
I'm struggling to find the replacement in workers. I've seen assets.html_handling which it seems I can use drop-trailing-slash for. Hoping that will work on all endpoints. What about the caching? Thanks

Both files are still supported in Workers just like Pages So you can keep using like you were

If you aren't seeing logs about them then yeah or your Wrangler version is too old. Try updating to latest

Ok thanks a lot. Looks like react router hasn't shipped their wrangler v4 update yet, will have another try at upgrading once this is released https://github.com/remix-run/react-router/pull/13258
