Bug ID: 60116 Summary: NC matches in the Rewrite Valve cause matched groups to be lower case. Product: Tomcat 8 Version: 8.5.x-trunk Hardware: All OS: All Status: NEW Severity: normal Priority: P2 Component: Catalina Assignee: dev@tomcat.apache.org Reporter: sebs...@sebster.com I have the following rewrite rule: RewriteCond %{REQUEST_URI} /test RewriteCond %{QUERY_STRING} .*a=([0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}).* [NC] RewriteRule .* - [E=X-Tenant-Id:%1,L] This matches the query string to the supplied pattern in a case insensitive way. However, the back reference %1 is always lower case, independent of the actual query string. That is, if the query string is: http://localhost:8080/test?a=CFA2AFDF-5D36-4D1F-B798-430557CF4355 the matched back reference %1 is cfa2afdf-5d36-4d1f-b798-430557cf4355. This is strange and unexpected. It is also not how NC works in The Apache HTTP server mod_rewrite, which just does the test in a case insensitive way but returns the actual matched group. Case insensitive Java regular expressions also do not change the case of any of the matched groups. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
