The problem is that your clients are sending unencoded characters which are not allowed by the spec. See https://bz.apache.org/bugzilla/show_bug.cgi?id=60594 or search the users list archives for 'RFC 7230' or 'RFC 3986' for more information. > How can I correct this in the tomcat configuration files? Search for 'tomcat.util.http.parser.HttpParser.requestTargetAllow' in http://tomcat.apache.org/tomcat-7.0-doc/config/systemprops.html to see what options are available. Presently you can allow {, }, and | but other characters will still yield a 400 response. > Thanks a lot, > > Paul Lueders > CLASSIFICATION: UNCLASSIFIED > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org > For additional commands, e-mail: users-h...@tomcat.apache.org > --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
