[solved] Let $cache expire with request

[thausmann]

Hello, I'm wondering if there is way to use $cache so it lasts exactly for one request, something like WireCache::expiresRequest?

Edit: I didn't think right, I can simply delete the cache when I'm done. And cache is probably overkill, in memory should be fine.

I wrote a cron php script that bootstraps ProcessWire and sends out some e-mails with an ICS file attached. 
I thought about caching the different files (the filepath to be precise) instead of generating the same over and over again.
