Hi, as I understand it, "Network.clearBrowserCache" clears only what is on the disk, but how to completely clean it?

Experimentally found such a way out, but how much is it true? If you observe in devtools that with a similar approach, nothing loads from the ram cache anymore.

Code: Select all

     Chromium1.ExecuteDevToolsMethod(0, 'Network.enable', nil);

     TempParams := TCefDictionaryValueRef.New;
     TempParams.SetBool('cacheDisabled', True);
     Chromium1.ExecuteDevToolsMethod(0, 'Network.setCacheDisabled', TempParams);

     Chromium1.ClearDataForOrigin('');
     Chromium1.ClearCache;

     TempParams := TCefDictionaryValueRef.New;
     TempParams.SetBool('cacheDisabled', False);
     Chromium1.ExecuteDevToolsMethod(0, 'Network.setCacheDisabled', TempParams);

     Chromium1.ExecuteDevToolsMethod(0, 'Network.disable', nil);

This can be achieved manually in devtools, check the "disable cache" box, then clean the cache and uncheck the disable box.

If clearing the cache in RAM is not working correctly then use a cache directory inside the temp directory given by System.IOUtils.TPath.GetTempPath

Then create a new browser with a new context that uses a different cache directory like :
C:\Users\<User name>\AppData\Local\Temp\cache001
C:\Users\<User name>\AppData\Local\Temp\cache002
C:\Users\<User name>\AppData\Local\Temp\cache003
