Conditional Rewrite in Apache 2: are these two Identical?

Can ...

RewriteCond %{REQUEST_URI} ^/folder1/ [OR]
RewriteCond %{REQUEST_URI} ^/folder2/ [OR]
RewriteCond %{REQUEST_URI} ^/folder3/
RewriteRule (.*) / [R=301,L]

... be rewritten to ...

RewriteCond %{REQUEST_URI} ^/(folder1|folder2|folder3开发者_如何学运维)/
RewriteRule (.*) / [R=301,L]

?

And if so, are they absolutey identical in functionality?

Suggestions/improvements are much appreciated.

They are the same thing, the | stands for OR so if it starts with /folder1/ or /folder2/ or /folder3/ do the redirect.

So yes it would be shorter and work out for your needs.

As Pekalski suggested you can make it shorter with:

^/folder[1-3]/
