@section vfs Virtual File Systems and Custom Schemes

with RegisterHandler() it will be called for all pages and resources.
-
- wxWebFileHandler is provided to allow the navigation of pages inside a zip
- archive. It overrides the @c file scheme and provides support for the
- standard @c file syntax as well as paths to archives of the form
- @c file:///C:/exmaple/docs.zip;protocol=zip/main.htm
