Ivan – can you explain your diagram in the context of our server discussion?

The first part of the diagram makes sense regardless of server – since the client could/may either send in ACCEPT headers and/or the server could just return whatever is the default.   No issues there.  NOTE: I do think there is a potential issue with the <link> in the HTML – but we’ll take that up separately.

Given a server w/o any additional code – even one configured to return different types – you would NEVER get extra headers returned.  So I am not sure how the second half of the diagram fits into your “simple server” model.  It is more aligned with my “extended server” models.  And if the server is “extended”, then why bother with the link (which also needs to be resolved, which isn’t covered in the diagram) and just put the entire M(partial) as the return.

Inspired by Ben, I have also created a diagram on the PWP Client behaviour when retrieving L:



The diagram is incomplete insofar as I have not added SVG as a possible return (which would be a possibility after all); it is a simplified version of the HTML branch, because there is no <link> element of the sort in SVG.

If you want to make any change, I used the https://www.draw.io/ service, and the corresponding XML file is also on the repo:


This is not an alternative to Ben's diagram, but a complement of it I guess.
