Need help with rewrite rule

[Nick Pearson]

I use an on-the-fly asset compacting/concatenating script for my apps, and
it works great.  The key is to cache the result so that it doesn't become a
bottleneck, as Igor pointed out.  If you just store the file with the URI
that was used to request it (commas and all), then this is as easy as page
caching.

So, if a request comes in for:

    /javascript/prototype.js,effects.js,builder.js

just cache the file at something like:

    [root]/tmp/cache/prototype.js,effects.js,builder.js

and serve that cached file the way you would any normal, cached HTML file
using either try_files or the "old" way of making sure the file exists and
rewriting the request.
