- Currently, it isn't possible to remove this header, but the value can be changed. By default, Privacy Browser sends a null (empty) value for the X-Requested-With header.
- Even though the spec allows for null header values, some web servers don't like them, so Privacy Browser has the option to revert to the default behavior of sending the app ID.
- Because this setting is cached when a URL is first loaded, and isn't changed when reloading a page or navigating history,
- changes to this setting may not be applied until Privacy Browser is restarted.
- There is a <a href="https://www.stoutner.com/the-x-requested-with-header/">blog post</a> with additional information.
- The X-Requested-With header will be <a href="https://redmine.stoutner.com/issues/37">completely removed</a> in the 4.x series with the release of Privacy WebView.</p>
