[undertow-dev] Disable URL decoding when rewriting

[Stuart Douglas]

Rewrite should not affect the encoding, except for query parameters
referenced through
io.undertow.server.HttpServerExchange#getQueryParameters() which are
always decoded.

Are you sure this is related to the rewrite? In general Undertow will
decode all URI's to UTF-8 by default. If you want your app to handle
all the encoding yourself you can set
io.undertow.UndertowOptions#DECODE_URL to false, which will prevent
Undertow from doing any decoding.

This does have some drawbacks though, mostly that it is a global
setting that affects all applications.
