Overview
This is a middleware that deflates response except for IE6. If your Rack application need support IE6, use this middleware instead of Rack::Deflater.
Usage:
require "racknga"
use Racknga::Middleware::Deflater
run YourApplication
You can use this middleware with Racknga::Middleware::Cache. You should use this middleware before the cache middleware:
use Racknga::Middleawre::Deflater
use Racknga::Middleawre::Cache, :database_path => "var/cache/db"
run YourApplication
If you use this middleware after the cache middleware, you get two problems. It’s the first problem pattern that the cache middleware may return deflated response to IE6. It’s the second problem pattern that the cache middleware may return not deflated response to no IE6 user agent. Here are examples:
Problem case:
use Racknga::Middleawre::Cache, :database_path => "var/cache/db"
use Racknga::Middleawre::Deflater
run YourApplication
Problem pattern1:
http://localhost:9292/ by Firefox -> no cache. cache deflated response.
http://localhost:9292/ by IE6 -> use deflated response cache.
Problem pattern2:
http://localhost:9292/ by IE6 -> no cache. cache not deflated response.
http://localhost:9292/ by Firefox -> use not deflated response cache.
