You can set Chrome as your default browser on Windows or Mac operating systems as well as your iPhone, iPad or Android device. When you set Chrome as your default browser, any link you click will automatically open in Chrome. This goes in your root .htaccess file but if you have access to httpd.conf that is better.
How do I make Chrome my default browser?
I purposefully redacted my personal irrelevant utility code. The freshness model (Section 4.2) does not necessarily apply to history mechanisms. That is, a history mechanism can display a previous representation even if it has expired.
Whenever possible ensure the cache-control HTTP header is set with no-cache, no-store, must-revalidate, private; and that the pragma HTTP header is set with no-cache. Where GITHUB_REF is a branch name (e.g. main) whose latest commit hash is used. That means that docker’s build cache is being invalidated only if the branch from which I build the image has had commits since the last run of docker build. 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.
Add Cache-Control Headers
- This goes in your root .htaccess file but if you have access to httpd.conf that is better.
- Moreover, specifically those tags are invalid in HTML5.
- To install Chrome, simply download the installation file, then look for it in your downloads folder.
- This is where you can manipulate the user agent (browser) cache to your liking.
- Use this middleware where-ever you intend to turn caching off.
These directives does not mitigate any security risk. They are really intended to force UA’s to refresh volatile information, not keep UA’s from being retaining information. At the very least, there is no guarantee that any routers, proxies, etc. will not ignore the caching directives as well. So we should use them with cautious overall when we are not in a local/dev environment.
Verifying the actual HTTP response headers
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. However, cacheing headers are unreliable in meta elements; for one, any web proxies between the site and the user will completely ignore them.
Originally we used no-cache many years ago and did run into some problems with stale content with certain browsers… There are different methods and if not specified, will use default. General differences between browser history and the normal HTTP caching are described in a specific sub-section of the spec. History buffers MAY store such responses as part of their normal operation. I must clarify that no-cache does not mean do not cache. In fact, it means «revalidate with server» before using any cached response you may have, on every request.
What is the difference between no-cache and no-store in Cache-control?
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. 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.
- The freshness model (Section 4.2) does not necessarily apply to history mechanisms.
- Public – may be cached in public shared caches.Private – may only be cached in private cache.No-Cache – may not be cached.No-Store – may be cached but not archived.
- I only want the caching to be applied to specific actions, not for all actions.
- 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.
- Also look into their offical docs for more ways to invalidate docker cache.
HTML meta tags vs HTTP response headers
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. If the client doesn’t specify a request type, the server will dictate it with Cache-Control. 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. Use this middleware where-ever you intend to turn caching off.
They include directives to declare what should be cacheable, what may be stored by caches, modifications of the expiration mechanism, and revalidation and reload controls. Additionally, jQuery and other client frameworks will attempt to trick the browser into not using its cached version of a resource by adding stuff to the url, like a timestamp or GUID. This is effective in making the browser ask for the resource again but doesn’t really prevent caching. 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.
That covers about 99% of all browsers in use as of Jan ’10. Other Cache-Control parameters such as max-age are irrelevant if the abovementioned Cache-Control parameters are specified. The Last-Modified header as included in most other answers here is only interesting if you actually want to cache the request, so you don’t need to specify it at all. The Cache-Control is per the HTTP 1.1 spec for clients and proxies (and implicitly required by some clients next to Expires). The Pragma is per the HTTP 1.0 spec for prehistoric clients.
The next chapter of Chrome
The list is just examples of different techniques, it’s not for directinsertion. 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.
Intermediate cache servers compatible with HTTP 1.1 will obey the same no-cache and must-revalidate instructions as browser caches will. After redirecting on ActionFilterAttribute event the consequences of clearing all headers are losing all session data and data in TempData storage. It’s safer to redirect from an Action or don’t clear headers when redirection is taking place. It will only apply to the index files and not other files you still might want to be cached. This may also come in handy if your dynamic files e.g. php, etc. are being cached by the browser, and you can’t figure out why. On a more positive note, policies regarding physical access to computers, software installation, and the like will put you miles ahead of most firms in terms of security.
Save time with autofill
If the server says that the resource is still valid then the cache can respond with its representation, thus alleviating the need for the server to resend the entire resource. I’m told to prevent user-info leaking, only «no-cache» in response is not enough. You can use pin up online casino nocache Middleware to turn off caching. Also, just for good measure, make sure you reset the ExpiresDefault in your .htaccess file if you’re using that to enable caching. On the other hand, if the server auto-includes a valid Date header, then you could theoretically omit Cache-Control too and rely on Expires only.
JQuery calls back to a controller action that returns results in JSON format. I have not been able to prove this, but I’m concerned that my data may be getting cached. I have a few RUN commands in my Dockerfile that I would like to run with -no-cache each time I build a Docker image. To answer the question, there are two players here, the client (request) and the server (response).
