Abstract This specification defines a number of additional link relation types that snippet of audio from a song, or a thumbnail representation of an image. in the response payload: HTTP/ OK Content-Type: text/html html>. Links that express other types of relationships have one or more link types specified in their source anchor. Since the A element has content (text, images, etc.). Browsers often use the MIME-type to determine what default action to do when text/plain text/html image/jpeg image/png audio/mpeg audio/ogg With the exception of multipart/form-data, that are used in relation of HTML.

The "privacy-policy" Link Relation and P3P. This specification defines and adds the following additional link relation types to the registry: Multiple subjects can be indicated through the use of multiple "about" link relations.
For example, an HTTP server that collects personal information about a user throughout the course of the user's interaction with the service can include "privacy-policy" links within all HTTP responses using any combination of Link headers or links embedded in the response payload: The linked resource can only be interpreted as a description of the expected practice.

The extent to which mechanisms are utilized is out of the scope of this specification, however. While the "privacy-policy" link relation can be used to reference P3P documents, there is no intended relationship, normative or otherwise, between this specification and the P3P Recommendation.
As far as this specification is concerned, P3P documents are just one possible type of resource that "privacy-policy" links can reference.
The terms of service can be any resource that describes the rules to which a consumer of the service must agree to follow when using the service provided by the link's context. For example, an HTTP server can include "terms-of-service" links within all HTTP responses using any combination of Link headers or links embedded in the response payload: The linked terms of service are simply a notice of the terms that may be expected to apply once a contract is established.
The "type" link relation references the payload's abstract semantic type, whereas the Content-Type header identifies the specific serialization format of the payload. This is possible but not recommended when applied to a non-composite body part: Once the message content has been delivered to an application, it is possible that subsequent processing may be affected by content type information indicated by the media feature expression.
Implementations must not assume a one-to-one relationship between 'Content-features' headers and contained body parts. Headers may appear on a containing multipart wrapper in a different order than the body parts to which they refer; a single header may refer to more than one contained body part; several headers may refer to the same contained body part.
If it is important to relate specific media features to specific contained MIME body parts, then the 'Content-features: The intent here is to allow summary media feature information to be provided without having to open up and examine the inner content of the MIME message.
Similar usage may apply when the message format is a non-MIME or opaque composite; e.
In these cases, the option of examining the message content to discover media feature information is not available. This part is a coverpage Content-Disposition: Security Considerations When applied to simple or multipart MIME formatted data, a media feature expression provides summary information about the message data, which in many cases can be determined by examination of the message content.
Under these circumstances, no additional security considerations appear to be raised. When applied to other message composites, especially encrypted message content, feature expressions may disclose information that is otherwise unavailable.
In these cases, some security considerations associated with media content negotiation [ 12 ] may have greater relevance. It is suggested here that media feature descriptions may be usefully employed with encrypted message content.

In doing this, take care to ensure that the purpose of encryption is not compromised e. This unprotected information could be tampered with, possibly fooling implementations into doing inappropriate things with the contained material.How to create table relationships in Access - dubaiairporthotel.info tutorial
Putting the media feature information inside the signed information would overcome this, at the cost of requiring implementations to parse the inner structure to find it.
