Hi Guys, Looking for help here after search on the web for couple hours:
I'm currently doing some testing on Tomcat 8.5.9 I'm trying to encode all the URL that is requesting to my server. One thing I have noticed it wasn't working is the `\` (back slash) can't be allowed in the URL. I'm getting the error saying: INFO [https-jsse-nio-8443-exec-10] org.apache.coyote.http11.Http11Processor.service Error parsing HTTP request header Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level. java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986 The test requesting URL is like this: https://localhost:8443/passthrough.jsp?ntUserName=comany\testuser Currenty, I tried those two approachs: 1st, set the server.xml with URIEncoding: http://tomcat.apache.org/tomcat-7.0-doc/config/http.html 2nd, add the following filter: https://wiki.apache.org/tomcat/FAQ/CharacterEncoding#Q1 It should be like this after the encoding (replace `\` with `%5C` ) : https://localhost:8443/passthrough.jsp?ntUserName=comany%5Ctestuser but none of those options worked for me. Thank you Charles Cai
