Hi,
I am using Wildfly 10.1.0.final which means undertow 1.4.0.final and I have the following
problem. I configured my app with
WEB-INF/undertow-handlers.conf :
path-prefix('/application') -> rewrite('${remaining}')
This works pretty well, but when the rewrite is triggered it seems to once decode my URL.
This is bad as my app will do the decoding at a central place once and thus the url will
be decoded twice if the endpoint is called via /application/...
How can I circumvent that undertow decodes my url before rewriting?
Thankx
Lukas

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.

Hi Stuart,
I am totally sure that my Path-Params get decoded twice and only if I use the rewrite
feature. I make the same request to <SERVER>.../id=%252524
Once via the rewrite, once without the rewrite. My application sends me back the ID it
received through JAX-RS PathParam and sends me back:
%2524 without and
%24 with rewrite
It is a simple JAX-RS Application without any decoding logic and only one rest endpoint. I
am not even sure where the one decoding happens that I want to have (should be Resteasy,
when it is providing the parameters to the resource method). But either way, if and only
if I use the undertow rewrite I get %24 which is incorrect ...
Please have a look into this...
I have the possibility to remote debug the undertow when this happens. If there is any
data I can provide to you that helps you track the error I am more than willing to do so
...
Bye
Lukas
