: How do I create flat link URL with .htaccess I am relatively new to URL rewriting. I recently created a forum and wishes to rewrite some of the thread URLs. I want to internally rewrite

I am relatively new to URL rewriting. I recently created a forum and wishes to rewrite some of the thread URLs.

I want to internally rewrite this link
example.com/306/slug-title/6 (on client side)

to this link
example.com/topic?id=306&slug=slug-title&page=6
(on server side)

I also want users who enter just only the topic ID without the slug title to be redirected (301: with their URL bar changed ) to the correct link where the slug title is included. For instance

A user who enters this link
example.com/306/6
should be 301 redirected to this link
example.com/306/slug-title/6
Which will then be internally re-written on the server side to this
example.com/topic?id=306&slug=slug-title&page=6
Please how do I go about this using URL rewriting.

NOTE: The behavior I want to achieve is exactly being exhibited by the link to this question

Remove the slug title

hit Go on your browser and you get sent back to the correct link

Although I have little knowledge of Regex, but a step by step guide will be highly appreciated.

Thanks.
