Hi, We are using tomcat-8.5.34. One of our client code is sending a POST request with HTTP header parameter "Host", as an empty string. And 8.5.34 version of tomcat is rejecting the connection with a 400 Error. After debugging, we found that the parseHost API in org.apache.coyote.AbstractProcessor is throwing an InvalidArgumentException (Seems to be introduced in 8.5.31). Then we checked out the latest tomcat code from SVN and found that the issue has been already addressed ( https://bz.apache.org/bugzilla/show_bug.cgi?id=62739 ) . So, we hope, the fix would be available in 8.5.35.
May I know, when is the next official tomcat release planned? So that we can decide on how to handle this issue in our product. Thanks, Mani
