title: Set Cache-Control on Google Cloud Storage bucket
body: <p>I have a bucket with public images that are frequently updated and would like to disable the default cache duration of 3600. (E.g. "Cache-Control:private, max-age=0, no-transform")</p>
  
  <p>Can the Cache-Control be set on a file while uploading it with PHP? </p>
  
  <p>Is there a way to set the default Cache-Control for all future files in the bucket (like with ACL that all files are public)?</p>
  
  <p>Right now I can only set it Cache-Control with gsutil and only for files currently on storage.</p>
