Description from extension meta

Utility that selectively overrides request caching and force fetches specific requests based on url patterns you provide.

Image from store Power Cache
Description from store Is the "disable cache" feature of Chrome's Dev Tools wasting you precious development time and costing you your sanity? Why not turn it off and only disable cache for selected paths/files? PowerCache save you time and gives you back your sanity by force-fetching specific assets, just the ones that you'd expect to have changed. Just add the URL pattern that you'd like to disable caching for and let it run. During web development, developers refresh web pages quite a bit. You can take advantage of caching for the vast majority of files, and only fetch new files for the features you're currently working on. It's easy to use: 1. Toggle off "Disable cache" on Chrome's network tab to take advantage of the vast majority of assets being loaded from cache making reloads faster. 2. Add the URL pattern for disabling cache and forcing requests of only specific assets (the ones you're likely working on) and enable it. The 'enable' button will be disabled until you specify a pattern. Patterns Patterns are NOT in regex format. They are simpler. Requests are inclusive of both "http://"; and "https://"; and assume them as well as any domain in the request prefixes automatically, so you don't have to worry about it. All that's needed is the tail end of the path, which can be as broad as all requests under first-level folders or as specific as single files. The extension also includes a help screen with additional information and examples of patterns. Patterns are automatically saved and synced across your account for easier reuse from the same or different machines. If you specify an incorrect pattern or if the pattern does not match any of the requests, you will not see any requests being logged in the 'Non-Cached Requests' panel.

  • (2020-07-30, v:0.0.5) Don Gordon: Doesn't seem to be working
    I have the pattern /themes/mytheme/* but requests to https://mysite.com/wp-content/themes/mytheme/style.css?ver=1.0.0 are not being caught by the plugin and are loading from local cache according to the developer console. I have Disable Cache unchecked and the pattern enabled in the plugin. Am I doing something wrong? Thanks

    This is my browser: Google Chrome 75.0.3770.100 (Build oficial) (64 bits) RevisiĆ³n cd0b15c8b6a4e70c44e27f35c37a4029bad3e3b0-refs/branch-heads/3770@{#1033} SO Mac OS X I installed the extension, refreshed the tab on which I wanted to use it put a "*" pattern, opened the dev tools, unchecked the "Disable Cache" in the "Network" tab and it still showed things returned from cache, closed Chrome, re-opened it, and still the same, hopefully you can help me check what is it that I have to do to make it work or if this is a bug. Thanks.
  • (2017-11-01, v:0.0.5) Sometimes doesn't work
    On some refreshes, Chrome will ignore the extension and give the status "200 OK (from memory cache)" for the matched items. Disabling then re-enabling the pattern then reloading fixes it. When it works it's great! Nitpicky detail: I noticed the timestamps don't respect my DST either.
