  • 1.  Tomcat 8.5 vs 9.0 for HTTP/1.0

    Posted 10 days ago

    Hello,
    Our architecture has a loadbalancer that checks Uniface by sending a HTTP 1.0 request on the main page of our application.

    It was working fine till Uniface 10.3.03/Tomcat 8.5. When switching to 10.4.02/Tomcat 9.0, Tomcat does  not accept the connexion (Error 400 in the logs).
    This is on a https connexion.
    Does anyone know whether we can get Tomcat 9.0 to accept HTTP 1.0 ? Is there a setup somewhere that would allow it ?

    So far our connexion string in server.xml looks like:
    <Connector port="8090" protocol="HTTP/1.1"
    connectionTimeout="20000"
    redirectPort="8091" />
    <Connector port="8091" maxThreads="150" scheme="https" secure="true" SSLEnabled="true"
    keystoreFile="conf/AVMEUPMCAPP01-02.p12" keystorePass="*****"
    clientAuth="false" keyAlias="tomcat" sslProtocol="TLS"/>
    It has not been the change during the migration.

    When we access the server directly through a browser, it works fine.

    Thanks,

    Stephane

    This issue has been solved. The loadbalancer had a wrong setting int the custom header.

    Tomcat 8.5 did not mind about a header that does not comply with the norm; however Tomcat 9.0 is not so much forgiving and that was leading to reject the request.

    The loadbalancer header has been corrected and it works now as expected.
