apache dispatcher rewrite query string rule

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.

    Your RewriteCond won’t match on the correct query string, your regex now says it should match on any string starting with a letter a-z or A-Z, then a number, then possibly multiple times ‘-‘. If you use https://regex101.com/ , you will notice that for example colourfilter=a9------ matches your regex, which is not correct. You can use ^colourfilter=([a-zA-Z0-9]*_[a-zA-Z0-9]*)$ as regex, that should match your example and fulfill your needs, with this regex any query string starting with a couple of numbers/letters then an underscore and then again some numbers or letters will match.

    You may try:

    (.*)/?(.*)

    Explanation of the above regex:

    (.*) – Represents first capturing group capturing the part of url before a query string leaving ?.

    /?(.*) – Represents a second capturing group capturing the query string part leaving the ?.

    $1.html/$2 – $1 represents the first captured group and $2 the second captured group. If $ doesn’t work try replacing with \. This will provide the necessary replacement.
