Working with Default HTTP Headers

Default HTTP Headers overview

Default HTTP Headers allow you to apply pre-defined set of HTTP headers automatically when you upload your files to Amazon S3.

This is a set of rules. Each rule consists of Bucket name (or mask) and File name (or mask) which identify one or more objects to which the rule applies and the Header Key and Header Value.

When you upload the file via S3 Browser, it looks up for the matching rule. If corresponding rule found, the header defined in the rule is automatically applied. If multiple rules found, the first matching rule is applied.

The rules are stored locally in S3 Browser settings folder. If you define the rules on a Machine A and then upload the files from the Machine B, the rules are not applied. You may transfer rules to another computer, they are located in the %APPDATA%\S3Browser folder in the file named bucket.rules.

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 Expires or the Content-Type header.

Bucket name and File name are optional fields. If you will leave them empty, S3 Browser will apply this header for any file you upload to any bucket.

For example if you would like to apply the Content-Disposition header to all *.exe files in a bucket called s3browser you add the following default HTTP header:

  • Bucket: s3browser
  • File name: *.exe
  • Header name: Content-Disposition
  • Header value: attachement

As you may note, the wildcards are allowed in bucket name and in the file name.
