Consolidating 3 rewrite rules into 1

is this the best way?

[StaceyJ]

I have a URL that looks like this

http://www.example.com/dir1/dir2/prodid.123456789

but /dir2 and /dir2/prodid.123456789 don't always have to exist. The following 3 rewrites have been tested and work to rewrite the new URL's back to the old filepaths

RewriteRule ^([^\./]+)/([^\./]+)/([^/]+)$ /cgi-bin/store/$1.cgi/$2/$3 [L]
RewriteRule ^([^\./]+)/([^\./]+)$ /cgi-bin/store/$1.cgi/$2 [L]
RewriteRule ^([^\./]+)$ /cgi-bin/store/$1.cgi [L]

I'd like to consolidate them if it would be more efficient, would this be the best way to accomplish that?

RewriteRule ^([^\./]+)([^\ ]+)* $ /cgi-bin/store/$1.cgi$2 [L]

I also think I could use (.*) instead for the second part, but I keep reading how it is best not to use it under various situations. Would that also apply here?

Thank you!

Include the slash preceding all optional subdirectories after the first level. I'd suggest:

RewriteRule ^([^/.]+)(/[^/.]+)*$ /cgi-bin/store/$1.cgi$2 [L]

It is not necessary to escape literal periods within alternate-character groups.
