I need to rewrite a URL with a query string into another URL.

For example, I have `https://www.something.com/cat/man/clothing/?colourfilter=blue_red`

It needs to be rewritten to `https://www.something.com/cat/man/clothing.html/colourfilter=blue_red`

I tried to follow the tutorial at <https://simonecarletti.com/blog/2009/01/apache-query-string-redirects/>

My current attempt is below:

```
RewriteCond %{QUERY_STRING} ^colourfilter=([a-zA-Z][0-9]-*)$
RewriteRule ^(.)$ (.*).html/colourfilter=%1 [R302,L]

```

I cannot get it to work.
