[jboss-jira] [JBoss JIRA] (WFLY-10648) curly brackets {} not working in url

[Jan Stourac (Jira)]

    [ https://issues.jboss.org/browse/WFLY-10648?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13687516#comment-13687516 ] 

Jan Stourac commented on WFLY-10648:
------------------------------------

Note that this starts to work when you percent-encode the curly brackets, so you use:
{code}
http://localhost:8080?q=%7B%7D
{code}
on your locally running WildFly (checked with WildFly 15). Although, it looks like common browsers (Firefox, Chrome) don't encode these. Based on [RFC1738|https://tools.ietf.org/html/rfc1738#section-2.2], curly brackets are supposed to be 'unsafe' characters and as such percent-encoded always. Although the RFC1738 has been obsoleted by [RFC3986|https://tools.ietf.org/html/rfc3986] which does not specify in any way.

Note there is a workaround to allow unescaped characters in URL for your listener:
{code}
/subsystem=undertow/server=default-server/http-listener=default:write-attribute(name=allow-unescaped-characters-in-url,value=true)
{code}
