That might not be possible.

Which illegal character (s) are the broken clients  sending?

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.

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.

Apache tomcat 7.0.82 RFC issue (UNCLASSIFIED)

2017-12-11 Thread Lueders, Paul T CIV USARMY NGIC (US) 
CLASSIFICATION: UNCLASSIFIED

I am running Apache tomcat 7.0.82.  It is not running behind any other web 
server.  I am getting:
Java.lang.IllegalArgumentException: Invalid Character found in the request 
target.  The valid characters are defined in RFC 7230 and RFC 3986

How can I correct this in the tomcat configuration files?

Thanks a lot,
