Save, restore or clear the current WebView's cookies and web storage

Vibium's storage command, on a WebView — mobium context WEBVIEW_... first.

With no argument, prints the page's storage state — its cookies, and its origin's localStorage and sessionStorage — in the shape Vibium saves, so a state saved by one restores in the other; -o writes it to a file. restore sets a saved state's cookies and writes each origin's storage only into a page on that origin. clear empties all three.

Usage

mobium storage [restore <file> | clear] [flags]

Flags

Flag	Type	Default	What it does
--output -o	string		write the state to this file (created 0600: its cookies are logins)

And the global flags.
