Description
In Eclipse Jetty, `TryPathsHandler` and `TryFilesFilter` can be configured to forward requests to template URIs such as `index?p=$path`, where `$path` is the request path in context.
However, URI paths may contain characters that are reserved in URI queries so that a path of `/s&a=1` when applied to the template becomes `index?p=/s&a=1`, which is interpreted as 2 query parameters: `p=/s` and `a=1`, rather than just one query parameter `p` whose value is `/s&a=1`.
