Tomcat 9 relaxedQueryChars format

[Robert Hicks]

What is the correct format?

I see the following used when I do a search:

relaxedQueryChars="[,],{,}.|"

relaxedQueryChars="[ ] { } |"

relaxedQueryChars="[]|{}^\`"<>"

We use that last one. I am running down this error:

java.lang.IllegalArgumentException: Invalid character found in the
request target. The valid characters are defined in RFC 7230 and RFC
3986

Thanks!
