If the no-cache directive does not specify a field-name, then a cache MUST NOT use the response to satisfy a subsequent request without successful revalidation with the origin server. In fact, it means “revalidate with server” before using any cached response you may have, on every request. The no-store header, on the other hand, prevents the data from being stored outside of a session, in which case it simply isn’t available for a history mechanism to use. With no-store, if the user ends his session by navigating to another domain and then goes back, the only way for browser to know what to display is to get the initial page again from the server. The Cache-Control header is used to specify directives for caching mechanisms in both HTTP requests and responses.
Perry said she’s “proud that I keep on swinging,” and reflected on the ups and downs of her long journey making pop music. “You KCs know I’m not one for anniversary posts,” the lengthy caption began. “I tend to be mostly a futurist but it would be negligent of me to not acknowledge the incredible impact this last year has had on me.”

The singer, 40, took to Instagram on Monday, September 22, to share several behind-the-scenes photos and videos, as well as a heartfelt letter to her fans. Have never looked back or had a single issue with stale content by any browser or intermediaries since. Originally we used no-cache many years ago and did run into some problems with stale content with certain browsers…
If no request happened during that period, the cache became stale and the next request will revalidate normally. If a cache supports must-understand, it stores the response with an understanding of cache requirements based on its status code. Aside from music, Perry also experienced a breakup from longtime partner Orlando Bloom in June, though the couple still seems to be friendly as they coparent their daughter, Daisy Dove.
Cache that exists between the origin server and clients (e.g., Proxy, CDN). It stores a single response and reuses it with multiple users — so developers should avoid storing personalized contents to be cached in the shared cache. My current understanding is that it is just for intermediate cache server.
Cache-Control header
In such a case, you could address the caching needs by using a specific, numbered version of the library, and including the hash of the picture in its URL. When you build static assets with versioning/hashing mechanisms, adding a version/hash to the filename or query string is a good way to manage caching. Revalidation will make the cache be fresh again, so it appears to clients that it was always fresh during that period — effectively hiding the latency penalty of revalidation from them. When you use a cache-busting pattern for resources and apply them to a long max-age, you can also add immutable to avoid revalidation.
Perry added that her fans have joined her on the “rollercoaster” of her career and most recent album release, and thanked them for “the community we are and growing to become.” In an Instagram post shared on Monday, Sept. 22, Perry, 40, reflected on the anniversary of the release of her 2024 album 143. Katy Perry achieved mainstream success in 2008 with her single “I Kissed a Girl,” which became a number one hit in multiple countries.

She rose to fame with One of the Boys (2008), a pop rock album containing her debut single “I Kissed a Girl” and follow-up single “Hot n Cold”, which reached number one and three on the U.S. The must-revalidate response directive indicates that the response can be stored in caches and can be reused while fresh. If the response becomes stale, it must be validated with the origin server before reuse. Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television personality. She is one of the best-selling music artists in history, having sold over 151 million records worldwide.

- General differences between browser history and the normal HTTP caching are described in a specific sub-section of the spec.
- The world’s highest-paid female musician in 2015 and 2018, Billboard named her one of the greatest pop stars of the 21st century.
- Must-revalidate is a way to prevent this from happening – either the stored response is revalidated with the origin server or a 504 (Gateway Timeout) response is generated.
- If you know the answer to “Can I reuse this?” is always no, you get a performance boost by skipping cache validation and saving room in the cache for other data.
Perry also said she is letting go of control and allowing her next steps to unfold naturally. “No forcing, no controlling — just trusting the angels, the fans, and the music to guide me where I’m meant to go,” she wrote. 143 was billed as a major pop comeback but faced backlash when fans learned producer Dr. Luke had contributed to the record. The lead single, “Woman’s World,” underperformed commercially, and the album drew the lowest Metacritic score in over a decade. “Records are snapshots of an artist trying to tell their story of where they are now or have been, and hope someone will hear themselves in some of the messages,” the post continued.
- The list is just examples of different techniques, it’s not for directinsertion.
- By contrast, no-store says to not even keep a copy, which means there’s nothing to ask about.
- Responses for requests with Authorization header fields must not be stored in a shared cache; however, the public directive will cause such responses to be stored in a shared cache.
- The intermediate cache server will decide whether using the saved content for following request.
- Client would ask server if it has new version of data using those headers and if the answer is no it will serve cached data.
- At 16, Perry released a gospel album titled Katy Hudson (2001) under Red Hill Records, which was unsuccessful.
Early life and debut album
Cache storage isn’t required to remove stale responses immediately because revalidation could change the response from being stale to being fresh again. This usually means the response can be reused for subsequent requests, depending on request directives. Touring in support of her new album, 143, the global pop superstar will be performing all of her hits, drawing from her extensive catalog. There are times when you may want to mix methods even on the same resource based on context. For example, you may want to use reload on a service worker and background sync, but use default for the web page itself.
Perry maintained her grip on the mainstream with her next release, Prism (2013), which produced, among other hits, the anthemic “Roar.” Her 2016 single “Rise” was featured in television coverage of that year’s Olympic Games in Rio de Janeiro. Perry’s fifth studio album, Witness (2017), more introspective than her earlier work, was less well received. She returned to mainstream pop with the empowerment-oriented Smile (2020).
The must-understand response directive indicates that a cache should store the response only if it understands the requirements for caching based on status code. If a request doesn’t have an Authorization header, or you are already using s-maxage or must-revalidate in the response, then you don’t need to use public. The no-store response directive indicates that any caches of any kind (private or shared) should not store this response. No-cache allows caches to store a response but requires them to revalidate it before reuse. If the sense of “don’t cache” that you want is actually “don’t store”, then no-store is the directive to use.
Perry later released 143(2024), which was notable for its negative reviews. Katy Perry tied Michael Jackson’s record of five number one songs from a single album when her song “Last Friday Night (T.G.I.F.)” reached the top of the Billboard Hot 100 chart in 2011. Any https://traderoom.info/why-users-choose-umarkets-forex-broker/ combination of client, or server can dictate what method, or set of methods, to use. If the server returns no-store, it’s not going to hit the cache, no matter what the client request type. If the client request was no-store, it doesn’t matter what the server returns, it won’t cache.
