Hello! I was quickly banned on some sites using CEF4. It was always fine with DCEF3 or with regular browsers
What can it be and can it be fixed ?? (I can pm you sites if needed)
Also I have problems with proxies. Cant turn it on, tried different proxytypes, setting it both in code or in IE settings

Hi,
Read this to configure proxies :

Here you have some suggestions about the "access denied" problem :

There are more info about that in Google. Search for : "the owner of this website has banned your access based on your browser's signature"

thanks, but links doesnt really help because sites have already blocked this browser... the fix can be only in the next update maybe?? browser needs new build and ID
you should check some security things in cef4 maybe?

Hi,
The browser signature can be calculated based on a combination of several things : user agent string, operating system, IP, screen resolution, cookies, preferred language, time zone, plugins installed, graphic card...
There's is no official formula to calculate the "browser signature" and as you can see in the sources, there is no "id" in CEF4Delphi.
Try this website to check how unique is your web browser :

LOL I am sorry. I was testing user-agent parameter and set it to "test" so many sites started to block me. I set it back and its okay!
THanks for the info and links anyway!
