AddUserMetaData Method
Adds meta data to an object.
Syntax
public void addUserMetaData(String key, String value);
Remarks
This method allows you to associate user meta data with an object. Before calling CreateObject use this method to add up to 2k of user meta data. The "x-amz-meta" prefix is added automatically and will be ignored if specified.
The meta data will be accessible through the Header when calling GetObject.
When unprintable characters are supplied, an "x-amz-missing-meta" header is returned from the server with a number which specifies the number of unprintable entries.
