Proxy

[Vaytl]

Hello.
Can you please tell me how to set up a proxy server for the browser?

The current version of WebView2 doesn't allow you to set the proxy settings so we have to use the Chromium command line switches.

GlobalWebView2Loader.ProxySettings is used to add these command line switches :

• if GlobalWebView2Loader.ProxySettings.NoProxyServer is TRUE then "--no-proxy-server" is added.
• if GlobalWebView2Loader.ProxySettings.AutoDetect is TRUE then "--proxy-auto-detect" is added.
• if you set some value to GlobalWebView2Loader.ProxySettings.Server then "--proxy-server" is added with that value.
• if you set some value to GlobalWebView2Loader.ProxySettings.ByPassList then "--proxy-bypass-list" is added with that value.
• if you set some value to GlobalWebView2Loader.ProxySettings.PacUrl then "--proxy-pac-url" is added with that value.

Read these documents for more information about those command line switches :

Thanks Salvadordf.

Please download WebView4Delphi again from GitHub.

I just fixed an issue assigning values to the proxy settings.

Thank you.
It was possible to set the proxy server only during initialization.
It didn't work after initialization.
Maybe I'm doing something wrong?

WebView2 has more limitations than CEF and at this moment we can't do that.
We can only configure it with a proxy before the GlobalWebView2Loader.StartWebView2 call.

Thank you very much, Salvadordf

Is there a chance in the future to make authorization support for a proxy?

[salvadordf]

Try adding the username and password to the URL in the GlobalWebView2Loader.ProxySettings.Server property :

Code: Select all

http://<user>:<pass>@<host>:<port>/

I'm still trying to find a way. Unfortunately, this line didn't help me. Maybe there are more ideas? I even tried to send messages via SendMessage to Webbrowser1.RenderCompHWND, but it doesn't notice any messages other than the click.
