Fonts and Images Get loaded multiple times

ghz 8months ago ⋅ 62 views

Some of my resources get reloaded multiple times (see below) even with a preload.

enter image description here

Notice that the fonts are reloaded twice. Same for the Icon-192.png.

What I tried so far:

<link 
   rel="preload" 
   href="assets/packages/font_awesome_flutter/lib/fonts/fa-solid-900.ttf"
   as="font" 
   crossorigin>

I tried with and without crossorigin.

It seems like you're experiencing issues with resources being reloaded multiple times despite using the <link rel="preload"> attribute. Here are a few things you can try to troubleshoot and potentially resolve the issue:

  1. Check Network Requests: Use browser developer tools (such as the Network tab in Chrome DevTools) to inspect the network requests. This will help you identify if the resources are indeed being reloaded multiple times, and if so, why.

  2. Review Resource URLs: Ensure that the URLs for the resources are consistent and correct. Sometimes, variations in URLs (e.g., query parameters) can cause resources to be loaded multiple times.

  3. Use Unique Identifiers: Make sure that each resource has a unique identifier in the HTML markup. This can prevent browsers from mistakenly treating similar resources as separate entities.

  4. Optimize Resource Loading: Optimize the loading of resources by minimizing unnecessary requests and leveraging caching mechanisms. This can include techniques such as combining CSS/JS files, using image sprites, and implementing server-side caching.

  5. Browser Cache Headers: Check the caching headers sent by the server for each resource. Ensure that the caching strategy is properly configured to allow browsers to cache resources effectively.

  6. Preload Resource Dependencies: If resources have dependencies (e.g., fonts referenced in CSS files), make sure to preload those dependencies as well to avoid unnecessary reloads.

  7. Use Resource Bundling: Consider bundling resources together to reduce the number of individual requests. Tools like Webpack or Gulp can help with bundling assets for optimized delivery.

  8. Browser Extensions and Plugins: Disable browser extensions or plugins temporarily to see if they are interfering with resource loading behavior.

  9. Test Across Browsers: Check if the issue persists across different browsers. It's possible that the behavior is specific to a particular browser or version.

  10. Consult Documentation and Forums: Review the documentation for the <link rel="preload"> attribute and related browser behavior. Additionally, search developer forums or communities to see if others have encountered similar issues and found solutions.

By systematically investigating these areas, you should be able to identify the root cause of the resource reloading issue and implement appropriate fixes.
