| Summary: | 0006090: Throttle Filter configuration with max-total-requests + timeout setting | ||||
| Description: |
I have a question regarding the Throttle Filter in Resin 4.0.50. Based on the documentation (http://www.caucho.com/resin-4.0/admin/filters.xtp#ThrottleFilter) [^] I did the following configuration: <filter filter-name="throttle" filter-class="com.caucho.filters.ThrottleFilter"> <init> <max-total-requests>10</max-total-requests> <timeout>60s</timeout> </init> </filter> <filter-mapping url-pattern="/*" filter-name="throttle"/> The Caucho documentation describes these two parameters as follows: max-total-requests => maximum number of requests allowed per IP within timeout timeout => interval for max-total-requests So I would expect that requests from certain IP address are handled like this: [17-09-02 18:01:00,890] Request allowed (0000001 in last 60s) [17-09-02 18:01:00,944] Request allowed (0000002 in last 60s) [17-09-02 18:01:00,994] Request allowed (0000003 in last 60s) [17-09-02 18:01:01,039] Request allowed (0000004 in last 60s) [17-09-02 18:01:01,092] Request allowed (0000005 in last 60s) [17-09-02 18:01:01,162] Request allowed (0000006 in last 60s) [17-09-02 18:01:01,212] Request allowed (0000007 in last 60s) [17-09-02 18:01:01,264] Request allowed (0000008 in last 60s) [17-09-02 18:01:01,306] Request allowed (0000009 in last 60s) [17-09-02 18:01:01,347] Request allowed (0000010 in last 60s) [17-09-02 18:01:01,398] Should be disallowed. Responding with 503 as there have been already 10 requests within the last 60 seconds. [17-09-02 18:01:01,440] Should be disallowed. Responding with 503 as there have been already 10 requests within the last 60 seconds. But all requests (even more than listed here) are processed without seeing any throttling effect at all. Is my understanding of the ThrottleFilter using above configuration wrong or is this a bug? |
