This tells the cache that it must submit the new client’s authentication information to the origin server before releasing the representation from the cache. > If you’d like such pages to be cacheable, but still authenticated for every user, combine the Cache-Control: public and no-cache headers. ![]() However, you can make authenticated pages public with a Cache-Control: public header HTTP 1.1-compliant caches will then allow them to be cached. Corresponds to the value of the private cache control directive. > By default, pages protected with HTTP authentication are considered private they will not be kept by shared caches. public class CacheControl extends Object. a browser cache) and must not be stored by a shared cache like Cloudflare or a corporate proxy. private Indicates the response message is intended for a single user (e.g. > My pages are password-protected how do proxy caches deal with them? public Indicates any cache may store the response, even if the response is normally non-cacheable or cacheable only within a private cache.

Is probably in the cached authenticated requests. This means not listing your private name servers with NS records in the public zone files. A private cache is only used by one client, only for the IP it was created for. As such, it gives a greater performance gain and a much greater scalability gain, as a user may receive cached copies of representations without ever having obtained a copy directly from the origin server. It is especially important, from a security standpoint, that the public server has no records of the private counterpart. A public, or shared cache is used by more than one client. A value of public permits caching by proxies and the client, whereas private disallows.
