TODO :
|
|
- manage SSL detection because if library isn't loaded, some bridge crash !
|
|
- factorize the annotation system
|
|
- factorize to adapter : Format, Bridge, Cache (actually code is almost the same)
|
|
- implement annotation cache for entrance page
|
|
- Cache : I think logic must be change as least to avoid to reconvert object from json in FileCache case.
|
|
- add namespace to avoid futur problem ?
|
|
- see FIXME mentions in the code
|
|
- implement header('X-Cached-Version: '.date(DATE_ATOM, filemtime($cachefile)));
