This didn’t work for me – using asp.net 4.5 the code runs but does’t produce the required result. Unfortunately, I don’t have any way to easily test this anymore, so I can’t say anything definitive about the latest versions of these browsers. The headers I’ve listed are the correct ones in order for responses from an HTTP 1.0 server to not be cached by browsers. On all other browsers I tested, they did fetch a fresh version from the server. On IE6, and Opera 9-10, hitting the back button still caused the cached version to be loaded. That covers about 99% of all browsers in use as of Jan ’10.
The platform joined the official list of operators approved by the Secretariat of Prizes and Betting of the Ministry of Finance in February 2025, following the approval of the sports betting regulatory framework in the country. Denise developed a sports betting platform and trading team to launch the business online in March 2001. CACHE option is used without the ORDER option, each instance caches a separate range of numbers and sequence numbers may be assigned out of order by the different instances. Is the sequence cache perform any significant role in performance? I could see the DBA team advises to set the sequence cache to a higher value at the time of performance optimization. The first line sets Cache-control to no-cache, and the second line adds the other attributes no-store, must-revalidate
Its product offering includes sports betting, online casino, online poker, and online bingo. The colouring for form is not very user friendly…. You’ve recently updated the form guide for football matches but it’s so confusing with the colours used. For a company that built itself around in play betting it’s a bit poor. I am happy with the company but the app has gone downhill

Right now, translation is in BETA, and doesn’t support every aspect of the game. You are free to use any assets or screenshots in your articles! Besides spending more time updating oracle data dictionary having small sequence caches can have other negative effects if you work with a Clustered Oracle installation. Using the CACHE and NOORDER options together results in the best performance for a sequence. If you omit both CACHE and NOCACHE, then the database caches 20 sequence numbers by default. Can any performance improvement be seen if I increase the cache value of SEQ_MY_SEQU_EMP_ID.

Many browsers will not cache https by default. The accepted answer is correct in which headers must be set, but not in how they must be set. Second calls to header() for Expires, Cache-control and Pragma completely overwrite previously set values. The spec indicates that the response must not be reused without revalidation. Older browsers may ignore this if they are not properly compliant to HTTP 1.1.
- The Cache-Control is per the HTTP 1.1 spec for clients and proxies (and implicitly required by some clients next to Expires).
- I tried this solution on IE 8 and found that the browser will load a cached version when you hit the back button.
- Browsers should validate freshness of cached stale content before using it, but it is not mandatory unless the additional directive must-revalidate is specified.
- Ideal HTTP cache control headers for different types of resources.
This means that a cache could store the file and then perform a conditional request to which the server could reply 304 NOT MODIFIED. I’ve edited it to remove incorrect information. Intermediate cache servers compatible with HTTP 1.1 will obey the same no-cache and must-revalidate instructions as browser caches will. Otherwise Chrome will show cached/buffered data when using the back button. In Chrome 34 (2014), it is still necessary to set no-store as well. General differences between browser history and the normal HTTP https://www.librarysites.info/learning-the-secrets-of/ caching are described in a specific sub-section of the spec.
EGaming Review magazine has ranked bet365 the number https://skillpoint.info/innovations-in-wood-carving-the-latest-tools-and-gadgets/ one Internet gaming company in 2010, 2011 and 2012 as part of its annual Power 50 list of the top 50 most influential Internet gaming companies. In March 2025, the company announced it was ceasing its services in China and other jurisdictions. In Brazil, the company established legal representation through a subsidiary, HS do Brasil Ltda.
- In Chrome 34 (2014), it is still necessary to set no-store as well.
- So to take advantage of this many (most?) caches will store no-cache responses.
- A work around is to set a short-living cookie with a constant name but a GUID value to create the illusion of an « authentication token ».
- It doesn’t hurt first load by a new user (aside from the proxy issue), but then subsequent navigation may be a lot slower.
- Is the sequence cache perform any significant role in performance?
In particular, I noticed that none of them would stop IE8 from using a cached version of the page when you accessed it by hitting the back button. Different browsers have their own subtle ways to disable the history buffer. Browsers special-case explicit must-revalidate to control history behavior. It doesn’t hurt first load by a new user (aside from the proxy issue), but then subsequent navigation may be a lot slower. @RamanGhai Disabling cache generally hurts performance (and all 3 options you’ve mentioned disable caching). How no-store , no-cache , must-revalidate affect performance ?
- India’s consumer affairs ministry served notices to various television channels and apps for promoting gambling companies and asked them to stop showing ads from bet365 and other betting platforms immediately.
- 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.
- I’m not sure which setting the browser will follow, but it’s unlikely to be consistent between browsers and versions.
- Also, ‘Autocomplete’ feature allows a browser to cache whatever the user types in an input field of a form.
- Will this have any side-effect on the performance of the website in terms of loading time ?
- JQuery calls back to a controller action that returns results in JSON format.
I do remember that in ASP.NET web forms and user controls, either this attribute or the VaryByControl attribute is required. The best you can do is provide suggestions that most browsers will honor, usually in the form of headers or meta tags. However, it should be noted that this attribute is non-standard (although it is supported by the major browsers) so it will break XHTML validation. It prevents all possibility of a cache hit, even with fresh resources. Setting both is useless, unless we are talking out-of-spec or HTTP/1.0 browsers that don’t support no-store (Maybe IE11?).
