[testing calibre]

hello everybody,
dear great Kovid.

preparations:
i created CA key and cert and signed with them a server cert signing request. now i installed the CA on the reading devices trusted root store (just another windows machine for now). then i configured the calibre server with the server certificate and key and added a user with write access. restartet the content server. now i can successfully use a browser on the other device to connect to calibre server and read books.

here the issue:
highliting and annotating text in the browser reader does not get synced back to the origin book in the library on the calibre server. interestingly when configuring another windows machine to connect and read the same book then i will get some (but not all) hightlights and annotations from the other machines browsers interactions. but the main book on the calibre servers machine always stays unhighlited / unannotated. when explicitly adding highlites and annotationis on the calibre servers machines book (calibre reader opened with calibre library manager app) they never get synced to the reading machines browser.

in every constellation i tried to explicitly hit the sync button on the reading machines browser and also tried to restart calibre server and reconnect the reading machines browser and forcefully reload the books. non of the intermediating steps yielded a successful syncronization.
