Bug ID: 69633
Summary: Filters mapped to "" are not applied to empty string
("") special URL pattern
Product: Tomcat 11
Version: 11.0.4
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Util
Assignee: dev@tomcat.apache.org
Reporter: gr.grzy...@gmail.com
Target Milestone: -------
I try to make Pax Web 10 based on Tomcat 11 (and Jetty 12 and Undertow 2.3)
compliant with OSGi CMPN TCK.
One of the failing tests is about applying filters mapped to "" when requesting
"root context" URI (like http://localhost:8080/).
https://jakarta.ee/specifications/servlet/6.1/jakarta-servlet-spec-6.1#specification-of-mappings
mentions this "special" pattern:
> The empty string ("") is a special URL
> pattern that exactly maps to the application’s
> context root, i.e., requests of the form
> http://host:port/<context-root> or
> http://host:port/<context-root>/.
> In this case the path info is "/" and the servlet
> path is empty string ("").
Nowhere in the Servlet API specification is stated that this mapping doesn't
related to Filter mappings too.
However in Tomcat
`org.apache.catalina.util.FilterUtil#matchFiltersURL(java.lang.String,
java.lang.String)`
we have:
// Case 4 - "Default" Match
return false; // NOTE - Not relevant for selecting filters
for testPath="" and requestPath="/"
I think this special condition should be added...
