You need call Chromium.UpdatePreferences after set proxy.

Hi,
I thought it wasn't possible to use the Tor network from a CEF based browser until I found this while searching for some background info to give you an answer :
https://www.codeproject.com/Articles/10 ... or-Browser
If you use the same kind of proxy to connect to the Tor network you would have to use these settings :
Code: Select all
TChromium.ProxyType := CEF_PROXYTYPE_FIXED_SERVERS;
TChromium.ProxyServer := '127.0.0.1';
TChromium.ProxyPort := 8182;
After setting the TChromium properties you can call TChromium.UpdatePreferences as Chinyaev said.

You only need to add
socks5:// to the sever address. It would be like this :
Code: Select all
TChromium.ProxyType := CEF_PROXYTYPE_FIXED_SERVERS;
TChromium.ProxyServer := 'socks5://127.0.0.1';
TChromium.ProxyPort := 8182;

Hi,
Try this :
Code: Select all
Chromium.ProxyType := CEF_PROXYTYPE_FIXED_SERVERS;
Chromium.ProxyServer := 'socks5://127.0.0.1'; // <--- just the scheme and server address.
Chromium.ProxyPort := 9050;
Chromium.UpdatePreferences;
I'm just "guessing" how it should be done because I don't have that proxy.
Is it available for free ?
Can you give a download link ?

Hi,
I've updated CEF4Delphi and now the MiniBrowser demo can select SOCKS proxy servers in the preferences :

I've tested a couple of SOCKS5 servers successfully.

Hi,
I'm afraid I can't do much more.
CEF4Delphi is just a CEF3 wrapper which includes Chromium. I can fix CEF4Delphi bugs but if there is a problem in CEF3 or Chromium we can only report the problem to the CEF3 project or to the Chromium project.
As far as I know, there's no way to change that timeout interval. It's buried in Chromium's code and it seems Google is ignoring these requests.
Read this from the official CEF3 forum :
http://magpcss.org/ceforum/viewtopic.php?f=6&t=13080
If possible, try configuring Tor to select a faster route.

Set TChromium.Options.ImageLoading to STATE_DISABLED
You can also use the TChromium.OnBeforeResourceLoad event and set Result to RV_CANCEL to cancel the request for the resources you don't want to load.

I forgot to mention that you should set TChromium.Options.ImageLoading before calling TChromium.CreateBrowser

This web page has a list of command line switches for Chromium. Not all of them work in CEF based applications but it's worth a try :
https://peter.sh/experiments/chromium-c ... -switches/
Use the GlobalCEFApp.AddCustomCommandLine function before the GlobalCEFApp.StartMainProcess call to test them.
For example GlobalCEFApp.AddCustomCommandLine('--show-fps-counter'); will show an FPS counter in the browser.
Some of those switches are related to the proxy servers, networking, etc.
