I would like to add the following rule in my urlrewrite.xml (Lucee server):

<from>^([a-zA-Z0-9\/\-\%\+:\[\]\{\}\|\;\<\>\?\,\*\!\@\#\$\ \(\)\^_`~]*)$</from>
<to type="passthrough">/index.cfm?furl=$1</to>

Any idea that could help me?

Does this answer your question? [What are invalid characters in XML](https://stackoverflow.com/questions/730133/what-are-invalid-characters-in-xml) — Enigmativity, Jun 08 '21 at 06:30
You have one large character set definition set inside square brackets [ ] and you are escaping lots of charachters inside, such as dot, asterisk and many more. MetaCharacters inside character sets are very different from the ones ouside: Only MetaCharacters that need to be escaped are the closing bracket ], the backslash \ and the caret ^. All others are considered being natural characters, hence you won't need to escape all of these. Please see "Metacharacters Inside Character Classes" in https://regular-expressions.mobi/charclass.html?wlr=1 — AndreasRu, Jun 08 '21 at 06:36

You're putting invalid characters in your XML value.

This is what it should be:

<from>^([a-zA-Z0-9\/\-\%\+:\[\]\{\}\|\;\&lt;\&gt;\?\,\*\!\@\#\$\ \(\)\^_`~]*)$</from>

These characters need to be escaped in XML:
