Tomcat 8 is not able to handle get request with '|' in query parameters?

Question

I am using Tomcat 8. In one case I need to handle external request coming from external source where the request has a parameters where it is separated by |.

Answer 1

The parameter tomcat.util.http.parser.HttpParser.requestTargetAllow is deprecated since Tomcat 8.5: tomcat official doc.

You can use relaxedQueryChars / relaxedPathChars in the connectors definition to allow these chars: tomcat official doc.
