 ** Suffix **   <a name="AmazonS3-Type-IndexDocument-Suffix"></a>
A suffix that is appended to a request that is for a directory on the website endpoint. (For example, if the suffix is `index.html` and you make a request to `samplebucket/images/`, the data that is returned will be for the object with the key name `images/index.html`.) The suffix must not be empty and must not include a slash character.  
Replacement must be made for object keys containing special characters (such as carriage returns) when using XML requests. For more information, see [ XML related object key constraints](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-keys.html#object-key-xml-related-constraints).
