class THTTPMessage: public TObject


THTTPMessage

A THTTPMessage object represents a generic HTTP request for the
Amazon S3 and the Google Storage services. It can easily be extended
to other API's. It assumes that each request is signed with the
client id and an encripted key, Base64(HMAC + SHA1 (HTTP Request))
which is based on a secret key provided in the constructor.
For more information about the authentication :
Google Storage:
http://code.google.com/apis/storage/docs/reference/v1/developer-guidev1.html#authentication
Amazon S3:
http://awsdocs.s3.amazonaws.com/S3/latest/s3-qrc.pdf
At the moment THTTPMessage is used for derived classes of TWebFile
(read only) files supporting HEAD and GET requests.
