We have many Angular applications, and we currently use Angular 15. I'm using Apache 2.4.57 and Tomcat 10.1.10/JDK20 on Windows 2019 (don't ask).
For several years now, I've used the following configuration without issues. Angular <-H2-> Apache <-MOD_JK/AJP 1.3--> Tomcat This week I've been working on replacing mod_jk with mod_http2, and for the most part, things are working, but I'm running into issues where we do HTTP POSTs of JSON to Rest APIs. We are using Spring Framework 6.0.10. The only things I have yet to try are upgrading to Tomcat 10.1.11 and updating to the latest JDK20 release. We are using Amazon Corretto. Angular <-H2-> Apache <-MOD_HTTP2/H2--> Tomcat Everything seems to be working fine except for places in our apps where we do things like a POST of JSON to a Rest API. To debug what's going on, I've enabled dumpio on Apache, and I can see the entire JSON getting posted. I've installed Wireshark on the backend where Tomcat is running, and I've captured the TCP packets containing the JSON, and I can see that the entire JSON is making it to Tomcat. When I compare the JSON in a diff tool, the JSON is the same, so I know it's making it intact. So I enabled FINE logging for HTTP2 on Tomcat, and I see everything looks to come through to Tomcat fine until it hits... org.apache.coyote.http2.Stream$StandardStreamInputBuffer.doRead The Stream input buffer is empty. Waiting for more data At this point, things hang for 20 seconds until a timeout occurs, and Tomcat closes the connection. Here's the odd thing, the same post doesn't always fail. In about 1 out of 10 attempts, the POST will succeed. When it does succeed and I compare the HTTP2 logs in Tomcat, everything looks the same until the end of the connection. Here are the logs showing a POST that succeeds vs. one that fails. Is there something we should be doing in our Angular apps differently when HTTP2 is used in place of AJP, or is this potentially a bug? Success... 11-Jul-2023 08:51:45.427 FINE [https-openssl-nio-exec-15] org.apache.coyote.http2.Http2UpgradeHandler.updateOverheadCount Connection [18], Stream [0], Frame type [HEADERS] resulted in new overhead count of [-260] 11-Jul-2023 08:51:45.427 FINE [https-openssl-nio-exec-15] org.apache.coyote.http2.Http2Parser.validateFrame Connection [18], Stream [0], Frame type [PING], Flags [1], Payload size [8] 11-Jul-2023 08:51:45.427 FINE [https-openssl-nio-exec-15] org.apache.coyote.http2.Http2UpgradeHandler$PingManager.receivePing Connection [18] Round trip time measured as [11,769,300]ns 11-Jul-2023 08:51:45.427 FINE [https-openssl-nio-exec-15] org.apache.coyote.http2.Http2Parser.validateFrame Connection [18], Stream [13], Frame type [DATA], Flags [0], Payload size [8000] 11-Jul-2023 08:51:45.427 FINE [https-openssl-nio-exec-15] org.apache.coyote.http2.Http2Parser.readDataFrame Connection [18], Stream [13], Data length [8000], Padding length [none] 11-Jul-2023 08:51:45.427 FINE [https-openssl-nio-exec-15] org.apache.coyote.http2.Http2UpgradeHandler.updateOverheadCount Connection [18], Stream [0], Frame type [DATA] resulted in new overhead count of [-280] 11-Jul-2023 08:51:45.428 FINE [https-openssl-nio-exec-15] org.apache.coyote.http2.Http2UpgradeHandler.startRequestBodyFrame Connection [18], Stream [13] startRequestBodyFrame returned [java.nio.HeapByteBuffer[pos=0 lim=65535 cap=65535]] 11-Jul-2023 08:51:45.428 FINE [https-openssl-nio-exec-15] org.apache.coyote.http2.Stream$StandardStreamInputBuffer.onDataAvailable Data added to inBuffer when read thread is waiting.
