So I need that url help.site.com will be redirected to jira.site.com/subfolder/subfolder1

How Can I do it?

Hello. I've resolved my issue

Just added http-request redirect to help.site.com frontend

acl ACL3 var(txn.txnhost) -m str -i help.site.com
http-request redirect code 301 location https://jira.site.com/subfolder/subfolder1 if ACL3
