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")
Can the Cache-Control be set on a file while uploading it with PHP?
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)?
Right now I can only set it Cache-Control with gsutil and only for files currently on storage.
You can set the Cache-Control while uploading an object - I suggest you use gsutil -D to see an example of the request it generates to do this, and then translate that to PHP:
gsutil -D -h Cache-Control:"Cache-Control:private, max-age=0, no-transform" \ cp file gs://your-bucket/file There's no way to set a default Cache-Control for the bucket.
Max: What's the typo you're referring to? When I run the command it works, and I see the specified Cache-Control in the debug output:
% gsutil -D -h Cache-Control:"Cache-Control:private, max-age=0, no-transform" cp file gs://my-bucket/file
