How to host static content pre-compressed in apache?

Question

I host a JavaScript game which basically consists of an .html and a .data file. If I compress them with gzip, their size shrinks to 25%. So I want to do that.

I'm not 100% sure, but I think using mod_gzip or mod_deflate does the compression on-the-fly, wasting cpu time all the time because the Content doesn't Change.

So I'ld like to precompile the Content. Therefore, I put a .gz next to the uncompressed files and put rewrite rules in .htaccess:

RewriteEngine on  # If client accepts compressed files  RewriteCond %{HTTP:Accept-Encoding} gzip  # and if compressed file exists  RewriteCond %{REQUEST_FILENAME}.gz -f  # send .html.gz instead of .html  RewriteRule ^(.+)\.(html|css|js|data)$ $1.$2.gz [T=text/$2,E=GZIP:gzip,L]  Header set Content-Encoding gzip env=GZIP  

The Redirect is working, I can request game.html and actually get deliviered game.html.gz. However, the browser doesn't just display it. Instead, it asks me where to save the file. How can I fix that? Or maybe there is another way to achieve my Goal?

This is how i fixed once the same problem.

Add new types in .htaccess:

AddEncoding gzip .jsgz .cssgz .htmlgz .datagz AddType application/javascript .jsgz AddType text/css .cssgz AddType text/html .htmlgz        AddType text/plain .datagz 

This was done this way because AddType instruction didn't accept extensions in the form .html.gz.

Then modify your rewrite rule:

RewriteRule ^(.+)\.(html|css|js|data)$ $1.$2gz [L]  

And finally rename your files. Remove dots from .html.gz, .js.gz and so on.

The full .htaccess would look like this:

AddEncoding gzip .jsgz .cssgz .htmlgz .datagz AddType application/x-javascript .jsgz AddType text/css .cssgz AddType text/html .htmlgz        AddType text/plain .datagz  RewriteEngine on  # If client accepts compressed files  RewriteCond %{HTTP:Accept-Encoding} gzip  # and if compressed file exists  RewriteCond %{REQUEST_FILENAME}gz -f  # send .html.gz instead of .html  RewriteRule ^(.+)\.(html|css|js|data)$ $1.$2gz [L]
