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.

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.

In 2013, Katy was appointed a UNICEF Goodwill Ambassador and has used her powerful voice to ensure every child’s right to health, education, equality, and protection. Perry’s post included behind-the-scenes photos and videos of the making of the album and Perry rehearsing onstage for the Lifetimes Tour. The tour is an encapsulation of Perry’s discography, including smash hits like “Firework,” “The One That Got Away” and “California Gurls.” Also no-store technically means must not store to any non-volatile storage (disk) and release it from volatile storage (memory) ASAP. A client request with no-store shouldn’t write to disk or database and is meant to transient. In reality, if you’re mixing up no-cache and no-store on the client, very little would change.
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.

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 https://traderoom.info/why-users-choose-umarkets-forex-broker/ in the shared cache. My current understanding is that it is just for intermediate cache server.
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.
Katy will launch the Lifetimes Tour in Mexico, with seven arena shows. In Australia, the demand for tickets to her initial eight arena shows was so strong that five shows were added. The summer will bring Katy back to North America where, in addition to crisscrossing the U.S., she’ll play seven sold-out arena shows in Canada. The mom of 5-year-old Daisy Dove (with Orlando) admitted that she’s entering her next era with ease as she wraps the final legs of her Lifetimes tour. While celebrating the first anniversary of 143, the 40-year-old looked back on the highs and lows she experienced since the album’s release. She ended her message to fans with optimism, writing, “Let’s hope we get to evolve together for years to come… and at the end of it all be proud and at peace with how we tried our best in this imperfect world.”
Directives
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.

This is where you can manipulate the user agent (browser) cache to your liking. Just remember that the server generally has the final say as to how the cache should work. No-store is effectively the full do not cache directive and is intended to prevent storage of the representation in any form of cache whatsoever. I’m told to prevent user-info leaking, only “no-cache” in response is not enough. 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. Use a no-cache to make sure that the HTML response itself is not cached.
stale-while-revalidate
If you forget to add private to a response with personalized content, then that response can be stored in a shared cache and end up being reused for multiple users, which can cause personal information to leak. The proxy-revalidate response directive is the equivalent of must-revalidate, but specifically for shared caches only. Ask the origin server whether or not the stored response is still fresh.
Bloom later told “Today” that the split was amicable and said, “We’re going to be great. Nothing but love.” The pop star reflected on both her professional setbacks and personal challenges, saying she feels “proud” of where she has landed. Katy Perry marked the first anniversary of her album 143 with a candid Instagram post about what she called a “rollercoaster” year. Perry, who recently split from ex Orlando Bloom and has been quietly seeing former Canadian prime minister Justin Trudeau, will take her globe-trotting Lifetimes Tour to Europe next month.
- 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).
- Note that s-maxage or must-revalidate also unlock that restriction.
- When you update the library or edit the picture, new content should have a new URL, and caches aren’t reused.
- 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.
- Perry said she’s “proud that I keep on swinging,” and reflected on the ups and downs of her long journey making pop music.
If the client doesn’t specify a request type, the server will dictate it with Cache-Control. For chrome, no-cache is used to reload the page on a re-visit, but it still caches it if you go back in history (back button). Adding no-cache to the response causes revalidation to the server, so you can serve a fresh response every time — or if the client already has a new one, just respond 304 Not Modified. If you don’t add a Cache-Control header because the response is not intended to be cached, that could cause an unexpected result. Cache storage is allowed to cache it heuristically — so if you have any requirements on caching, you should always indicate them explicitly, in the Cache-Control header. For example, a request with the header above indicates that the browser will accept a stale response from the cache that has expired within the last hour.
- “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.
- Chrome and Firefox specifically does not work with these as you would expect, if at all.
- 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.”

Even if “no-cache” is in response, intermediate cache server can still save the content to non-volatile storage. The intermediate cache server will decide whether using the saved content for following request. However, if “no-store” is in the response, the intermediate cache sever is not supposed to store the content. The no-store request directive allows a client to request that caches refrain from storing the request and corresponding response — even if the origin server’s response could be stored. Since Katy Perry’s Capitol Records debut in 2008 with One of the Boys, she has racked up a cumulative 115 billion streams alongside worldwide sales of over 70 million adjusted albums and 143 million tracks. Katy now has six singles and one album for a total of SEVEN Diamond-certified titles.
After recording the stripped-down live album MTV Unplugged (2009), Perry returned to the studio. Perry’s initial efforts at mainstream stardom were fruitless, with two separate record labels signing and subsequently dropping her before any material was released. In 2007, however, Capitol Records put out Perry’s EP Ur So Gay, which attracted modest attention for its cheerfully flippant title track. She made a greater splash several months later with the single “I Kissed a Girl,” an assertive ode to sexual curiosity backed by a hard-edged electro-pop beat. The song quickly stirred controversy, as some critics derided it for promoting same-sex relations and others charged that the racy scenario it depicted catered to male fantasies of female sexuality. Nevertheless, the combination of titillation and polished melodicism helped “I Kissed a Girl” become a number one hit in multiple countries, powering sales for her album One of the Boys (2008).
The immutable response directive indicates that the response will not be updated while it’s fresh. No-transform indicates that any intermediary (regardless of whether it implements a cache) shouldn’t transform the response contents. Note that s-maxage or must-revalidate also unlock that restriction. The pop star said she’s “trusting the angels” to guide her from here on out.
