WebKit2.Settings.allow_file_access_from_file_urls

Settings.allow_file_access_from_file_urls: Boolean (Read / Write / Construct)
  

Whether file access is allowed from file URLs. By default, when something is loaded in a WebKit2.WebView using a file URI, cross origin requests to other file resources are not allowed. This setting allows you to change that behaviour, so that it would be possible to do a XMLHttpRequest of a local file, for example.

Since 2.10
