1721579 - intercept request "replace a network request with a local file from apk"

Status: UNCONFIRMED

(GeckoView :: General, enhancement, P3)

Description

Attachment: intercept.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:90.0) Gecko/20100101 Firefox/90.0

Steps to reproduce:

I'm trying to load something from the apk with a resource address from a server. For example a request to the address https://example.com/app/index.html is intercepted to get it from an index.html file in the apk and the request to the server is not made.

Actual results:

The issue is that I need to keep the domain "https://example.com" I can't change this address to resource://, moz-extension://, data:text/html,<data> because I'm going to fall into some block when using other features such as service-worker.

Expected results:

It is possible to perform this type of intercept request using android webview.

Two examples where this type of intercept request can be found:
