When a page generates a LDAP query that returns a huge number of records, then all of them are processed on the backend to generate a HTML page containing all the results. Pagination is completely handled on the frontend side, hiding/showing elements corresponding to the page number.

There are drawbacks to this approach:

• when the HTML page is too long to generate, the request may reach reverse-proxies timeout
• the response may be very huge (measured >50MB)

The pagination system architecture should be reconsidered to only return current page of results and request the backend at each page change.
