How do I gzip webpage output with Rails?

Question

What is the best plugin for Rails that gzips my webpage output?

Edit: The company I am hosting with has stated they will not install mod_deflate.

Answer 1

Unless you are running your Rails application without another webserver (which usually isn't a great idea), you should probably look at your webserver. All major webservers have options to enable gzip. For example, for Apache, you can use mod_deflate.

Answer 2

Have you tested to see if it's already enabled? If your hosting provider uses Apache it very well could be there by default.

Run this command against your site and see if you get the Content-Encoding: gzip header.

$ curl --head -H "Accept-Encoding: gzip" http://example.com

Answer 3

Have you tried using the deflate middleware? Add use Rack::Deflater to your config.ru.

It's how you'd do it with an app running on Heroku (AFAIK since cedar-stack).

Answer 4

If your hosting company does not support mod_deflate it's time for a new hosting company. I think doing this in Ruby would be pretty slow and a pain in the butt.

Answer 5

Have you tried enabling compression in apache via mod_deflate?
