While 3.3 has this behavior as the default, it can be disabled in the config
by:
<DecodeInterceptor safe="false" />
Since the release is scheduled to happen by the end of the month, you might
consider jumping straight to 3.3.

Subject: URI handling in tomcat 3.2.3
> Hi everyone,
>
> we were in progress of moving our project to tomcat 3.2.3 when we came
> accross the new handling of URIs (release-notes sec. 7.2).
>
> Since we are using the URI to transport other hierarchical information
> then filesystem paths, we have the feeling, that this kind of
> functionality belongs to the default servlet serving filesystem
> requests. Especialy the fact that %25, %2E, %2F and %5c inside an URI
> lead to a 404 error seems to somewhat strange.
> For Example:
http://server/app/UCB/vnd.sun.star.hier:%2F/address/myresource
> would be rejected, before app has teh possibilty to look at the request
> and ...hier://address/myfile... would be normalized to hier:/address.
>
> We are perfectly aware of the security concerns behind these changes.
> However, they only apply when serving resources from the filesystem. A
> URL's path-components however are in no way bound to the representaion
> of filesystem paths.(After all, the U in URL stands for universal :)
>
> RFC 2396 states that '/' in an URI has another semantic meaning then %2F
> in an URI. The '/' seperates path-components, while the %2F means a
> slash character in a path-component. When such an URI is mapped to a
> filesystem this would denote a filename that contains a slash. When the
> system does not allow for such names, it is the responsebilty of the
> filesystem servlet to report an error (404 since such a file must not
> exist on unix for example).

> What are your opinions on this?
