AJAX :: Clear Browser Cache With Script?
Jul 26, 2011
OK, so I have an AJAX app and am using browser caching to reduce the number of server calls. However, I wanted to be able to clear the whole cache for the browser if the version of my AJAX app has changed.
My plan is to have the version number stored in a cookie on a user's machine. The first thing my app then does upon load is check the version number of the javascript to the version number of the cookie and if they are not the same clear the cache.
Is this possible?

Hint me about an easy and clear way to cache ajax response into client browser WITHOUT using the JQuery? I am unable to find that on google.
I have a page that is loaded using AJAX and it takes long time to load every time (approximately 28 seconds), so I need to cache it to reduce the time. I tried the stored procedure for database, but it did not give me good result, so I want to try the caching.

I have a client that wants a site for people who are potentailly being abused, often by partners they live with.
He is under the impression that it is possible for there to be a "Button" that deletes the cache when the user presses it rather than going through the procedure of clearing the cache. I can see why this would be a goog thing to have, and wondered of js (or perhaps php might be the way to go)

I am working on a online video portal build on flash/actionScript.
If I enter a url of a video when another video is playing, it doesn't playing the new video but it keeps on playing the old video. The reason I think is as it is a RIA, it doesn't refreshes the page and looks for a flash object and its already cached so it doesn't makes any http request in order to play the new video.
So I am planning to claer the cache.
how to clear the cache when a user enters something in address bar and press enter key?

Is there a way in Javascript, or perhaps in HTML, to force a browser to
re-render an image on an HTML page after a round-trip between the client
and the server ?
In my particular case, the image is changing on the server although the
URL for it remains the same, but the browser is still displaying the old
image from its cache rather than the new image from its URL location.

Using IE 5.5(sp2) no other!
I have several .js files that are included in various jsp pages.
I've read somewhere(can't remember where?) that the browser caches .js
files.
If this is the case is it better to include all of them in the 1st page of
my app regardless if they're used in this page & take a performance hit
once? - or am I missing something?

Does anybody know how to make FireFox to cache data that comes via
XMLHttpRequest? Here is the issue I deal with:
- On the web server (apache2) I have a static xml file test.xml
- When I download test.xml using XMLHttpRequest, FireFox always gets
complete test.xml from the server, thus not using the browser cache
(apache sends 200 OK back to FireFox).
- If I look into the HTTP request and the HTTP response, I can see
that FireFox seems to always set the following request headers:
Pragma: no-cache
Cache-Control: no-cache
- Apache always sets Last-Modified and ETag headers in a response.
I tried the same JavaScript code with IE, and IE definitely relies on
its cache: I can see in Apache logs responses with 304 Not Modified
code for IE, also HTTP requests from IE have If-Modified-Since and
If-None-Match headers. I didn't find any difference in responses Apache
provides for FireFox and IE.

I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?

Have an issue with using $.ajax for requests. If I set async: false it works fine, but sometimes gets cached content. If I add in cache: false then async doesn't work anymore, the next ajax request gets called before the first one finishes.

In part of my form, I have 3 inputs (one textarea and two text inputs),I am validating their value format using AJAX (each input triggers error message on its label in case format is wrong). Also I have one button, "NOT submit button" (type = button).Now, when clicking on the button it must enter the value of those three inputs in my database in case they are true then all inputs values must be cleared. In case AJAX validation is wrong and in case the user clicked on that button, the value of fields must kept as it is.
Actually I can not use submit button because I have it for the whole form and what I am taking about is a part of the form and it's not possible to make nested forms as I know it violates html rules. It's easy to make it if I am taking about submitting button as I can view session values on fields after submission in case ajax returns error.I can clear inputs from Javascript, but it will be cleared on both cases if AJAX validation true or wrong. Each input field has AJAX Error message that will be triggered when the input format is wrong.

I'm looking to upgrade some of my scripts to AJAX (right now I'm sending info back and forth between an iframe), but wanted to make sure I wasn't losing some cross-browser compatibility by doing so. I saw this double checker on one of the tutorials and liked it, but I want to make sure it isn't limiting any other common (maybe even slightly older) browsers:
