How to create an htaccess rule?

Question

htaccess

Good afternoon, tell me how to create a rule for htaccess that will allow you to receive url as a variable.
For example mysite.com/bla/id/ google.com/search/12
In this case, it is necessary that on the site mysite.com in the bla directory the id should get the value google.com/search/12
I did it as follows:

RewriteRule ^bla/id/([A-Za-z0-9-]+)/?$ dir/dir/index.php?id=$1 [NC,L]

If you have any ideas, please tell me.

Answer 1

RewriteRule ^bla/id/([\\/_A-Za-z0-9-]+)/?$  index.php?id=$1 [NC,L]
