Subject: Support proxying bulk Read API requests for access rights
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=25468fa7e64263758f6b3d5741802ac462e029f9;p=contrib%2FConifer.git

Support proxying bulk Read API requests for access rights

Using IP-based access right determination runs into problems with a pure
JavaScript API, as users may be accessing the API from any location in
the world. Proxying the requests via the library system server ensures
that the access rights for users of those libraries are properly
displayed.
