[solved] Clear cache for one (currect) site only?

[postcd]

Hello,
i apologize if this is not right section, pls delete if wrong.

I seek an extension (v.57 compatible) that can clear cache for particular webpage (current web page), not all cache.
Is there any work around, is it possible to clear just on one site?

my FF: 57.0b9 32bit

There are cache related extensions:
https://addons.mozilla.org/en-US/firefo ... form=linux

I used "Clear Site Cache" but it seems to be not longer supported in v. 57.

clearing the site cache ever was futile with this built-in function or a button which includes loading and without cache where you have to clear and reload in two actions.

why simple when it can be complicated.

It's not possible to just clear the cached contents of the current site with the WebExtensions API.

Is there any workaround?

Are you a web developer? Do you want code to run in scratchpad in the browser context?

Try this:

* open about:config tab
* set devtools.chrome.enabled pref to true
* tools > web developer > scratchpad
* environment > browser
* edit > paste (i.e. copy and paste code snippet)
* select a tab for clearing
* execute > run

Code: Select all

(function () {

  if (typeof document.getElementsByAttribute == "undefined") {

    alert("Scratchpad: not in browser context");

  } else {

    function humanBytes(bytes) {
      if (bytes < 1024) {
        return bytes + " bytes";
      } else if (bytes < 1024 * 1024) {
        return Math.round(bytes / 10.24) / 100 + " KB";
      } else {
        return Math.round(bytes / 10.24 / 1024) / 100 + " MB";
      }
    }

    try {
      var uri = gBrowser.currentURI;
      var stats = {
        host: uri.host, removed: null, total_size: null,
      };
    } catch (e) { alert("Scratchpad: can't get host"); return; }

    var cacheService = Components.classes["@mozilla.org/netwerk/cache-storage-service;1"].
      getService(Components.interfaces.nsICacheStorageService);
    var loadContextInfo = Components.classes["@mozilla.org/load-context-info-factory;1"].
      getService(Components.interfaces.nsILoadContextInfoFactory);
    cacheService.diskCacheStorage(loadContextInfo.default, false).asyncVisitStorage({
      onCacheStorageInfo: function () {},
      onCacheEntryInfo: function (aURI, aIdEnhance, aDataSize) {
        if (stats.host !== aURI.host) return;
        stats.removed++;
        stats.total_size += aDataSize;
        cacheService.diskCacheStorage(loadContextInfo.default, false).
          asyncDoomURI(uri, null, null);
      },
      onCacheEntryVisitCompleted: function () {
        alert("Scratchpad: " + (0 + stats.removed) + " entries removed (" +
          humanBytes(0 + stats.total_size) + ")");
      },
    }, true);

  }

})();

That code works for me in Fx 57.
