Set Cache-Control no-cache for static resources in development mode.

This won't work without the modifications I made to simple_bridge:

nitrogen/simple_bridge#21

[evanmiller]

Thanks.

In production the old behavior should be restored (a long cache period, e.g. 10 years).

Also viewing the diff above, there appears to be something wacky in the patch's spacing.

I will wait to see what Jesse decided on nitrogen/simple_bridge#21 before moving forward.

I'm not positive that setting an Expires is the best course of action - isn't the 'if-modified-since' system a little bit more robust if someone actually does change the file in question?

[evanmiller]

That's a good point. "Expires" does seem to be causing some headaches for people in production, and I think folks who want high-performance static assets will choose other solutions (Nginx, S3, etc).

I'm OK with the proposed changes as they stand, then. In the future it would be nice to support If-Modified-Since or ETag somehow.

[davidw]

I don't know what's doing it, but my application is happily returning 304's for static requests, which seems right to me.

[evanmiller]

Well by George! Perhaps some under-the-hat Cowboy magic is at work.

I'd like to include this change in the next release, so if we don't hear from Jesse I'll just point rebar.config at your branch.

[evanmiller]

OK -- looks like Jesse got your SimpleBridge changes merged in, so I will go ahead and merge this in and update the SimpleBridge version as well. Thanks for your patience!
