Commit https://github.com/spring-projects/spring-framework/commit/2b97d6 introduced a change where the path within the DispatcherServlet is determined with each call to ResourceUrlProvider.getForRequestUrl. To avoid repeating that every time a URL is encoded through the response, we now cache the result of the lookupPath determination in ResourceUrlEncodingFilter. Issue: SPR-12332
