Find centralized, trusted content and collaborate around the technologies you use most. Many browsers use this directive for reloading, as explained below. After the stale-if-error period passes, the client will receive any error generated. This feature is well established and works across many devices and browser versions.

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.

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.
The no-store directive applies to the entire message and indicates that the cache must not store any part of the response or any request that asked for it. The stale-if-error request directive indicates that the browser is interested in receiving stale content on error from any intermediate server for a particular origin.This is not supported by any browser (see Browser compatibility). The client indicates that an already-cached response should be returned. If a cache has a stored response, even a stale one, it will be returned. If no cached response is available, a 504 Gateway Timeout response will be returned.
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.

No-cache allows clients to request the most up-to-date response even if the cache has a fresh response. In a lengthy post on Instagram, the pop star reflected on the “incredible impact” she’s felt since releasing her album 143, taking stock of all the twists and turns she’s faced in the process. “Records are snapshots of an artist trying to tell their story,” she wrote on Instagram, adding that 143 has become about “reconnecting” with her fans on tour.
An explaination of the HTTP Cache-Control header
The public response directive indicates that the response can be stored in a shared cache. 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. If you want caches to always check for content updates while reusing stored content, no-cache is the directive to use. It does this by requiring caches to revalidate each request with the origin server. The Grammy nominee shared a slideshow of photos and videos from the past year, including behind-the-scenes images from the “Woman’s World” music video shoot and moments from her tour stops.
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.
Response Directives
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 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.

At 16, Perry released a gospel album titled Katy Hudson (2001) under Red Hill Records, which was unsuccessful. She moved to Los Angeles at 17 to venture into secular music, and later adopted her stage name from her mother’s maiden name. Perry recorded an album while signed to Columbia Records, but was dropped before signing to Capitol Records.
- By then, however, Hudson had found new musical models in such rock artists as Freddie Mercury and Alanis Morissette, whom she had discovered through friends.
- If the server returns no-store, it’s not going to hit the cache, no matter what the client request type.
- As a teenager, she learned to play the guitar and sought a musical career in Nashville with a Christian record label, but her debut album, the gospel-influenced Katy Hudson (2001), sold poorly.
- The client indicates that an already-cached response should be returned.
To answer the question, there are two players here, the client (request) and the server (response). If a caching system correctly implements no-store, then you wouldn’t need no-cache. Additionally, some browsers implement no-cache like it was no-store.
- After the stale-if-error period passes, the client will receive any error generated.
- There are times when you may want to mix methods even on the same resource based on context.
- You can add a long max-age value and immutable because the content will never change.
- There are no cache directives for clearing already-stored responses from caches on intermediate servers.
- In reality, if you’re mixing up no-cache and no-store on the client, very little would change.
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.
If copied, the second would overwrite the first and thefourth would overwrite the third because of the http-equivdeclarations AND fail with the W3C validator. At most, one could haveone of each http-equiv declarations; pragma, cache-control andexpires. These are completely outdated when using modern up to date browsers.After IE9 anyway. Chrome and Firefox specifically does not work with these as you would expect, if at all. Note that the major browsers do not support requests with min-fresh. Browsers usually add no-cache to requests when users are force reloading a page.
September will bring her to South America, where her arena dates in Buenos Aires are sold out and limited tickets remain for her stadium show in Chile. Katy will wrap up the 2025 tour in the UK and Europe, where popular demand led to multiple added shows in London, Paris, and new shows in Munich and Bologna. Beyond her music, Perry’s personal life continues to draw attention. Nearly two months after being spotted with former Canadian Prime Minister Justin Trudeau, the two are “still speaking and very interested in each other,” multiple sources told US Weekly. Perry, 40, told fans that she usually avoids anniversary posts but felt compelled to recognize the impact of the past year.
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 https://traderoom.info/why-users-choose-umarkets-forex-broker/ 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…
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.
The stale-if-error response directive indicates that the cache can reuse a stale response when an upstream server generates an error, or when the error is generated locally. Here, an error is considered any response with a status code of 500, 502, 503, or 504. In the example above, the response is fresh for 7 days (604800s).After 7 days it becomes stale, but the cache is allowed to reuse it for any requests that are made in the following day (86400s), provided that they revalidate the response in the background.
As a teenager, she learned to play the guitar and sought a musical career in Nashville with a Christian record label, but her debut album, the gospel-influenced Katy Hudson (2001), sold poorly. By then, however, Hudson had found new musical models in such rock artists as Freddie Mercury and Alanis Morissette, whom she had discovered through friends. She soon moved to Los Angeles to pursue success in the secular music realm, adopting her mother’s maiden name, Perry, to avoid confusion with the actress Kate Hudson. The no-cache directive in a response indicates that the response must not be used to serve a subsequent request i.e. the cache must not display a response that has this directive set in the header but must let the server serve the request. The no-cache directive can include some field names; in which case the response can be shown from the cache except for the field names specified which should be served from the server.
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).
As you identified, no-cache doesn’t mean there is never caching, but rather that the user agent has to always ask the server if it’s OK to use what it cached. By contrast, no-store says to not even keep a copy, which means there’s nothing to ask about. 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. Imagine that clients/caches store a fresh response for a path, with no request flight to the server. The no-cache request directive asks caches to validate the response with the origin server before reuse. When a user reloads the browser, the browser will send conditional requests for validating to the origin server.
