filling localStorage and sessionStorage

[ray007]

I have a local webapp running in the CefSharp view which sometimes loads an external webapp from the server.
When detecting the address change to load the external app, I'm using ExecuteScriptAsync to add some items to localStorage and sessionStorage.

This worked fine with ancient CefSharp 85, after upgrading to version 103 it does not work anymore.
Looking at developer tools, the data has not been added to the storages and the script is found anonymously under "(no domain)" instead of the target domain.

Has anything changed here? What can I do so my webapp will find the data in localStorage and sessionStorage again?

Update:
It seems when I just execute the script from the address change or FrameLoadStart event the storages aren't yet bound to the target domain and therefore not found by the js application.

If I use webView.WebBrowser.ExecuteScriptAsyncWhenPageLoaded(scriptData), the storage is filled late and the js app already tried to read data and didn't find it.

Any idea how I can prefill localStorage and sessionStorage so the js app finds the data on startup?

You can try using the Chrome DevTools protocol.

Not yet sure how that could help me, but I'll read up on that, thank you.

Tried to inject the data using the devclient DOMStorage api, but that didn't help so far.
