> I am trying to use knox as a proxy for superset which is a flask application. 
> Flask applications have behave differently when we add or remove trailing slash in the URL. 
> In superset we have urls both with and without trailing slash and the expected behavior is to keep trailing ‘/‘ if its in the input URL I.e do exact match for the path and substitute it in template including trailing ‘/'. 
> Consider the case of of these two URLs - 
> 1) /users/list/
> 2) /users/add
> Now when I use following rewrite rule - 
> {code}
> <rule dir="IN" name="SUPERSET-UI/superset-ui/inbound/path" pattern="*://*:*/**/superset-ui/{path=**}">
>   <rewrite template="{$serviceUrl[SUPERSET-UI]}/{path=**}"/>
> </rule>
> {code}
> It removes trailing slash from all the urls matching urls.
> The expected behavior for knox is to preserve trailing '/' in the urls while rewriting.
