Tomcat 9 Http2 Without Ssl
- Sub-Component - Coyote OS: Redhat Linux Overview: Embedded Tomcat version 9.0.39 is implemented to transport http/2 packets between 2 systems (h2c connection). Http2 packets of payload size 55KB sent from the client are processed asynchronously. The content-type of request/response is application/json.
- Running Tomcat 9.0.34 and $ curl -version curl 7.63.0 (x8664-w64-mingw32) libcurl/7.63.0 OpenSSL/1.1.1a (WinSSL) zlib/1.2.11 libidn2/2.0.5 nghttp2/1.35.1 Release-Date: 2018-12-12 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smtp smtps telnet tftp Features: AsynchDNS IDN IPv6 Largefile SSPI Kerberos.
- In a recent Security Advisory, Apache Software Foundation has released a patch for CVE-2020-13943, a flaw in Tomcat HTTP/2 Request Mixup. According to Apache, if an HTTP/2 client exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it could have been possible that a subsequent request made on that connection contains HTTP headers.
- By default Tomcat will ignore all trailer headers when processing HTTP/2 connections. For a header to be processed, it must be added to this comma-separated list of header names. InitialWindowSize: Controls the initial size of the flow control window for streams that Tomcat advertises to clients.
