Feature request: automatic redirection

There are quite a few services available to make websites more usable on devices like the ReMarkable, such as frogfind which strips them down to simple HTML where possible (http://frogfind.com/about.php).

It would make for great UX to be able to set up automatic redirects in the form of sprintf/regex/whatever patterns - for example to prefix `http://frogfind.com/read.php?a=` to urls.
