Hi, I believe that mod_deflate compresses a particular resource on-the-fly each time the resource is requested. Is this true? This repetitive compression seems a bit wasteful for a resource that doesn't change often. I would like to set up the following type of caching system or something similar if possible to speed things up. A client requests a file /javascripts/ajax.js. Apache receives the request and examines the request to determine if the browser can handle the gzip format. If the browser can then apache looks for a file called /javascripts/ajax.js.gz. If the last modified date on /javascripts/ajax.js.gz is newer than the last modified date on /javascripts/ajax.js then apache sends /javascripts/ajax.js.gz to the browser. If the last modified date on /javascripts/ajax.js.gz is older than /javascripts/ajax.js then Apache (or a script that apache calls) makes a new version of /javascripts/ajax.js.gz and send this new version to the browser. If the browser cannot handle the gzip format then apache just sends /javascripts/ajax.js Is this possible? Is this very tricky? Is there an easier way?
