Microsoft Internet Explorer cannot load certain webpages when passing through GFI WebMonitor. The following error is encountered:
HTTP Error 406 - Not acceptable
- GFI WebMonitor
- All supported environments
Configure the browser to avoid changing the Accept-Encoding Header by GFI WebMonitor.
- Open Internet Explorer
- Navigate to Settings > Internet Options
- Click the Advanced tab
- Uncheck the HTTP 1.1 through proxy connections option
GFI WebMonitor can only process plain text encoding and that's why it sends the request to the Web servers with Accept-Encoding: FFFF,FFFFFF header, but certain web servers do not accept this kind of header value, hence return a 406 error to the HTTP client.
