Working with Default HTTP Headers Default HTTP Headers overview Default HTTP Headers is feature that let's you automatically apply pre-defined set of HTTP headers to files you upload to Amazon S3. You may configure it in a way that specific headers will be applied to subset of files or buckets, or even all files you upload to Amazon S3 via TntDrive. Flexible masks with wildcards support are available for bucket and file names. Using this feature you may automatically apply storage classes (x-amz-storage-class), permissions (x-amz-acl), server-side encryption (x-amz-server-side-encryption) and other s3-specific headers for files during uploading. You may also modify some standard HTTP headers like the Conntent-Type or Expires header.

If you leave them empty, the filter will be applied to all files you upload to any bucket. If you would like to apply the header only to files in specific bucket, you need to specify the bucket name. If need to apply the header only to files in specific folder in a bucket, you also specify the folder name with the /* at the end. For example if you need to apply custom Content-Type header only to files in the my-files folder in a bucket called my-stuff you need to add the following default HTTP header: - Bucket: my-stuff
- File name: my-files/*
- header name: Conntent-Type
- header value: my-custom/content-type
For example if you need to apply the Expires header only to *.png files in a bucket called my-images you need to add the following default HTTP header: - Bucket: my-images
- File name: *.png
