@RubenGarcia our WebView Unity plugin exposes a subset of what's available with the underlying CoreWebView2 control. You can find the current API surface area here: https://learn.microsoft.com/en-us/windows/mixed-reality/develop/advanced-concepts/webview2-unity-plugin. We don't currently expose a method for clearing the cache. We can look into that.

Yes, clearing the cache would be very useful.
Please expose it.
Thank you.

@RubenGarcia are you interested in clearing everything? Browsing history, cookies, temp files, etc.?

My usecase is being able to change the html in a webpage, and seeing the changes in WebView2. Right now, if I change the webpage, Webview2 shows the old, cached page.

Another thing which I would like exposed is a way to get and set the ZoomFactor.
This is especially important since wheel functionality to traverse long pages is currently not working

Could you give a few more details on your scenario? I did some quick testing, but didn't hit a caching issue. Is the page hosted locally? How is the HTML modified? I assume you're refreshing and expecting the updated content?

I browsed
https://rubengarcia.userweb.mwn.de/videos/
with hololens.
Then closed the program
Then used sftp to upload a new page with a different background colour to https://rubengarcia.userweb.mwn.de/videos/index.html
Then I opened the hololens again, and the page displayed the old background colour.

@RubenGarcia how are you closing the app?

In hololens, tap on wrist, click on the button at the bottom of the menu, then long press on app name in menu, then close.
