Disable mod_deflate

I am looking for a way to disable it...

Can you confirm that the mod_deflate is still a problem? In the words of @karlitschek: Nowadays we no longer do compression with php so mod_deflate should be ok. On my test machine mod_deflate is activated and seems to work fine.

Unfortunately mod_deflate is compulsorily enabled inside the apache2::web_app definition. So perhaps the best way to disable it is adding SetEnv no-gzip 1 to the VirtualHost template.

I can confirm this 100%(!). I double checked it with Safari, Firefox, but it does not happen with wget.

If I use SetEnv no-gzip in the .htaccess file I get the exact file back, checked by its md5.
If I don't enable this option get a slightly smaller file:

78991231 20 Mai 17:08 with-gizp.tar.gz
79320952 20 Mai 17:07 no-gzip.tar.gz

$ md5 with-gizp.tar.gz
c222245d374d63f6f5560c4ad95541db

$ md5 no-gzip.tar.gz
f7a88e46fb62689142ebf24b3592cc3e

$ md5 original-file.tar.gz
f7a88e46fb62689142ebf24b3592cc3e

Hi @schmunk42,

I've made a patch, but tried to disable mod_deflate only on downloads, so the html, css, etc. will still be gzipped: adce32a

Do you think this will be enough or maybe it is better to disable completely?

[schmunk42]

I think it is enough, if these are all the "exit points" when downloading a file.

Maybe this is also only an issue with .tar.gz files, but someone would have to investigate this in detail, thank you!
