Chrome.webrequest Cross-origin Disallowed Scheme On Redirect To Data:

I'm using chrome.webRequest api to intercept xhr's and redirect to a saved blob i have in chrome.storage.local and get this error: XMLHttpRequest cannot load http://test.com/bla.xm

Solution 1:

Redirecting to data:-URIs is fully supported by the webRequest API (and you don't need the non-existent data:* permission for it).

Your requests failed because data:-URI access through XMLHttpRequest was not supported until Chrome 39. (Starting in Chrome 39, you will be able to fetch data:-URIs using XMLHttpRequest, see http://crbug.com/308768 for more info).
