natural commented on issue #4125: NIFI-7153 Adds ContentLengthFilter and DoSFilter URL: https://github.com/apache/nifi/pull/4125#issuecomment-603408254 > @natural if you can show me what I am doing wrong or resolve the issue with the log output, I will make the minor formatting changes I pointed out and merge this. I believe you tripped the internal form-length filter because `curl` is sending a multipart form. When I PUT json directly: ```$ openssl rand -hex 30240000 > /tmp/hexdata $ http -p Hh PUT :8080/nifi-api/processors/0da1088c-0171-1000-da90-5ddb7f242ee1 foo=@/tmp/hexdata PUT /nifi-api/processors/0da1088c-0171-1000-da90-5ddb7f242ee1 HTTP/1.1 Accept: application/json, */* Accept-Encoding: gzip, deflate Connection: keep-alive Content-Length: 60480013 Content-Type: application/json Host: localhost:8080 User-Agent: HTTPie/1.0.2 HTTP/1.1 413 Payload Too Large Content-Length: 17 Content-Security-Policy: frame-ancestors 'self' Content-Type: text/plain Date: Tue, 24 Mar 2020 17:51:08 GMT Server: Jetty(9.4.19.v20190610) X-Frame-Options: SAMEORIGIN X-XSS-Protection: 1; mode=block ``` I have the log entries as expected: `2020-03-24 09:51:08,932 WARN [NiFi Web Server-18] o.a.n.w.s.requests.ContentLengthFilter Content length check rejected request with content-length 60480013 greater than maximum 20971520 B`
