Hi, The mention of using "NOT character ('!')" in rule patterns as negative match no longer matches implementation:
https://tomcat.apache.org/tomcat-8.5-doc/rewrite.html In the rules, the NOT character ('!') is also available as a possible > pattern prefix. This enables you to negate a pattern; to say, for instance: > ``*if the current URL does NOT match this pattern*''. This can be used > for exceptional cases, where it is easier to match the negative pattern, or > as a last default rule. > The current implementation uses java.util.regex, which does not support a simple ! prefix as a negative match regex: https://docs.oracle.com/javase/8/docs/api/index.html?java/util/regex/Pattern.html Instead, you need to use zero-width lookahead like this (to match any URL but /portal/api/.*) ^(?!/portal/api/.*).*$ This inaccurate documentation exist in all versions, at least since 8.0.x. For backward compatibility to the above documentation, RewriteRule needs the `positive` variable and logic found in the RewriteCond class. https://bz.apache.org/bugzilla/show_bug.cgi?id=63608 Thanks --Michael . -- CONFIDENTIALITY NOTICE: This e-mail, including attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information or otherwise be protected by law.
