python-ldap中SimplePagedResultsControl中的'criticality'属性是什么？

Question

我正在使用python-ldap对LDAP搜索进行分页。
我在网上找到了很多类似的参考资料，它们都设置了：page_control = SimplePagedResultsControl(True, size={some_size}, cookie='')
例如：https://medium.com/@alpolishchuk/pagination-of-ldap-search-results-with-python-ldap-845de60b90d2
我检查了python-ldap的文档，找不到有用的解释：

https://www.python-ldap.org/en/latest/reference/ldap-controls.html#ldap.controls.libldap.SimplePagedResultsControl

Answer 1

我找到了答案：https://www.rfc-editor.org/rfc/rfc2696

If the server does not support pagedResultsControl, 
the server MUST return an error of unsupportedCriticalExtension if the client
requested it as critical, otherwise the server SHOULD ignore the control.
