Member since: Sep Posted 11 Sep Link to this post I am also running into the same problem.
Any ideas what the correct fix for this is? I've seen mention of using headers, but I'm not sure how to apply a fix in this situation. Browsers treat them just like other HTTP requests.
You can fully control how the browser caches your content using HTTP headers. Just press f12then go to network tab and find the forth button in tool box with this title : Always refresh from server.
It will send request each time with no cache. After a lot of searching and troubleshooting, I finally found the solution to fix this. Adding the header Cache-Control:no-cache did not work, it actually fouled up the troubleshooting in my case.
And the Cache-Control header fixed it to http 1. According to a defect in the Microsoft database, the Pragma header is ignored if there is a Cache-Control header:. Learn more.

Have you tried adding a timestamp to the query-string parameters?
I've used that to force CSS files to not be cached. Caching ajax requests is a common issue and browsers tend to cache more and more aggresively. An additional request parameter that carries a timestamp value is a common workaround. Active Oldest Votes. Ben Ben 2, 20 20 silver badges 30 30 bronze badges.

They are asking how to make this work for all users of their web app. It's usually not feasible to ask each and every user to make changes to their browser settings.AJAX is everywhere and jQuery offers a nice simple API to easily create AJAX requests, what not many people know though, is that it also provides ways to ease the burden of callback hell which accompanies asynchronous code!
It does so by giving us promises. So far, so good, now imagine I make several calls to that AJAX function, it makes sense to create a more generic function to wrap my repeated functionality. Turns out jQuery AJAX functions already return a promise, as stated before promises are just objects will eventually be resolved. We just pass a callback to the done function! For example. The Promise exposes only the Deferred methods needed to attach additional handlers or determine the state then, done, fail, always, pipe, progress, and statebut not ones that change the state resolve, reject, notify, resolveWith, rejectWith, and notifyWith.
A nice thing about promises is that if we call done once the promise has been resolved, the callback is called instantly! Knowins this we can rewrite our little cache as follows. Assume we want to load several songs at once, and we have to wait to get all songs before doing the rendering, with regular callbacks this is hell! You have to chain AJAX calls inside callbacks and such!
As you can see the when function is itself a promise which resolves once all the promises inside it has been resolved, using it we solved our previous problem in a short, maintainable and elegant way! You should use them whenever you have the chance to avoid the issues exposed in this article. For more information on deferreds I highly recommend watching this short video of jQuery conf which very nicely explains a lot about them.How to clear the session state in Oracle Application Express?
First of all, I have created couple of hidden page items as above. Now I want to set the values for these two items on page load. I wanted to delete a record from the table based on page item value. So before the item has been deleted I wanted to get and set the values for those items in the hidden fields.
What happen in the above script? Now, I want to add an ajax post request to send the delete request to remote server. This request will basically delete the record from the external site when the record is delete from the internal system.
Now this will work fine but the problem is after the AJAX post request APEX page still holds the session variables for these two hidden items and it will execute the script again and again on every page load unless we can clear the session state somehow without logging out of the application.

Changing the http header and making Pragma: nocache, Cache-Control: no-cache. In ASP you can use. Also you can use html META tag.
Add following tag in head of your html page. I was searching for a solution for quit a while — thanks million times!!! Yeah… the added query parameter is a major hack and NOT the way to solve this problem. This is the purpose of the directive s. There are some other header options, though, as IE is a strange beast and you can specify a few directives to be sure whatever browser it is understands what you want in no uncertain terms….
This addresses the cache concern without all the potential side effects related to having unpredictable URLs and using a feature not intended to address this issue. Use the right tool for the job and your life will be easier in the long run. Put a border around it like every other field!! Design people! Hi Alex, Thanks for the comment. Changed the background to lighter shade. Try to use xhr. Different URLs cannot prevent from caching the useless data.
Hi I am new one for here…i am using one concept. Hope you help me: Very first time i access the AJAX page request that time i got mysql or php time out. After alert i do the same action. Nowadays with MVC frameworks and the popularization of url rewriting to map query string params to url segments…. Sometimes it may be more useful to use either a POST parameter rather than a GET — or force no-cache in the response headers server side. Thats a great solution.
I was spending nights with this issue for a longtime. When I searched online. It worked like a charm. Hello viral………. Its very useful blog, which have solved my headache of IE cache. Thanx 4 sharing it.
Thanks a lot : i test every thing to solve this problem but not work! Thanks a lot : I faced this problem multiple time during my prgming. Hi Gourav, Thank you very much …. Very helpful…. Thanks a lot. This solution works perfectly. Many, many kudos to you, sir!This article is by guest author Peter Bengtsson.
Clear session state in Oracle APEX after an AJAX action
You could use a global variable as your cache, something like this:. That just relies on a global variable to hold the cached data. The immediate problem is that the cached data goes away if you reload the page or navigate to some new page.
The second problem is that this solution is very specific to a particular URL and a particular piece of cached data key information in this example. What we want is a generic solution that is based on the URL instead. And now you want to wrap that, so that repeated network calls can benefit from a local cache.Google cache removal request
The second time it should draw directly from the local storage. This works, but is useless, of course. The first promise returned by fetch actually goes ahead and makes the GET request. The most interesting feature is that we have to clone the Response object returned by the first promise.
This is because sessionStorage can only store text. So our first implementation just takes care of storing the responses of requests. What we need to do is return, first of all, a promise and the promise needs to resolve a Response object.
Since the sessionStorage. And only if there was something there, do we return the cached result. If not, the if statement just carries on to the regular code.

A better solution is to give the user control instead. The user in this case is the web developer using our cachedFetch function. Like with storage such as Memcached or Redis on the server side, you set a lifetime specifying how long it should be cached. Now, neither sessionStorage nor localStorage has this functionality built-in, so we have to implement it manually.
But before we do that, how is this going to look? How about something like this:. But note that now we can also switch to the braver storage of localStorage instead of sessionStorage. Not only are we avoiding hitting those web APIs excessively, the best part is that localStorage is a gazillion times faster than relying on network. It measures other things but basically concludes that localStorage is really fast and disk-cache warm-ups are rare.
We would need a bit more code.
