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]
