Add all keys and values as defined by w3.org: make it easy to add them to entity httpheader. Maybe by making attributes ‘key’ and ‘value’ via enums, or even listing them in the documentation of the attribute ‘key’ and ‘ value’ would help.
This will put an end to the need to have to look for the exact names, capitals, ‘-’ and ‘/’
I see no apperent solution for headers that are not in the list of standard http headers. That is why I put the alternative in as well: add them to the documentation of Httpheader-entity. That should be possible to implement within one hour.
How would you handle headers that are not in the list of standard http headers?
