Hi, we recently upgrade our tomcat from 7.0.91 to 7.0.94 in windows platform. Post upgrade we are seeing the below exception in logs very frequently. can you please suggest to avoid this.
Dec 02, 2019 1:34:09 PM org.apache.coyote.http11.AbstractHttp11Processor process INFO: Error parsing HTTP request header Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level. java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986 at org.apache.coyote.http11.InternalInputBuffer.parseRequestLine(InternalInputBuffer.java:199) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1050) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:637) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:319) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.base/java.lang.Thread.run(Thread.java:830) And will this effect anything? as I didn't receive any complaints from users. Thanks Ram
