php - how to specify cache validator for Google fonts -


gtmetrix result

specify cache validator (92) - server high what's mean? following resources missing cache validator. resources not specify cache validator cannot refreshed efficiently. specify last-modified or etag header enable cache validation following resources:

http://fonts.googleapis.com/css?family=lato%3a100%2c100italic%2c300%2c300italic%2cregular%2citalic%2c700%2c700italic%2c900%2c900italic&ver=4.6.1 http://fonts.googleapis.com/css?family=lato%3a100%2c300%2c400%2c600%2c700%2c900%7copen+sans%3a700%2c300%2c600%2c400%7craleway%3a900%7cplayfair+display%7c&ver=4.6.1

the check you've performed complaining there not being either last-modified or etag header on resources being served fonts.googleapis.com site.

unfortunately there isn't can (i assume) not in charge of servers. if want rid of warning can fonts google servers , serve them own server. can setup caching headers way want.

note though, not of issue. thing happens when these headers missing caching may not work according way validator expecting. there nothing end-user notice this.
