This module provides a set of objects which can serialize and deserialize complex HTTP header types. This is useful if you need to interrogate the values in these headers for specific purposes such as content negotiation, link following, etc.
The following headers are supported:
- Link
- as specificed in [http://tools.ietf.org/html/rfc5988]
- Content-Type
- as specified in [http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.7]
- Accept
- parses each media type and organizes them into a priority list
- Accept-Charset, Accept-Encoding and Accept-Language
- parses into a priority list
- Date, Expires, Last-Modified, If-Unmodified-Since and If-Modified-Since
- parses into a Date object (which is just a wrapped Time::Piece object)
- Authorization, Authentication-Info and WWW-Authenticate
- this will handle Basic, Digest when appropriate
- follows the examples in [http://www.ietf.org/rfc/rfc2617.txt]
- this will handle Basic, Digest when appropriate
There is plans to support these headers as well:
- Content-Disposition
- as specified in [http://www.ietf.org/rfc/rfc2183.txt]
- User-Agent
- should use a module for this since it is such a mess
- Content-Range and Range
- basic range parsing
And if we ever need them, we can support these headers as well:
- Cache-Control
- there are lots of things here, but eventually we might need it
- Expect
- not even really sure what this would need, but its a possibility
