General rewrite rule question v2

[[email protected] Profile]

I have a working rewrite rule that I just want some opinion on. Currently using rewrite v2. NOT upgrading to v3.

I use the following:
RewriteRule ^(.*)\.spp[a-fA-F0-9]+\.(css|js|png|gif|jpg|jpeg|ico|woff|ttf|eot|svg|swf) $1.$2 [I]

Which will rewrite URLs such as: foo.a0b1.jpg -> foo.jpg

It works well, but I wanted opinion if:
1) I'm using the best syntax.
2) I'd like to make the rule a bit more versatile as to support ANY file extension so as I support more file type, I don't have to modify my rule each time.
3) What's the best way to query string append (QSA) in v2. v2 does not seem to support the QSA directive.

Thanks in advance.

Hello, Marc

Here's how I see the best way to write your rule accounting for all your requirements:

RewriteRule /(.*)\.spp[a-fA-F0-9]+\.(\w+)(?:\?(.+))? /$1.$2(?3\?$3) [I,L]

Hope this works, but I think it is only applicable for version 2, right?
