Disable gzip compression for zip files

[Florian Hackenberger]

Binary package hint: apache

According to [1],[2] and [3], we have to apply a workaround to our apache configuration to enable users of IE to download zip files from our webserver. We added '|zip' to the following line in '/etc/apache2/sites-available/default' and 'default-ssl':

SetEnvIfNoCase REQUEST_URI .(?:gif|jp?g|png|zip)$ no-gzip dont-vary

Although this is certainly not a bug in apache, Ubuntu should include this workaround in the default configuration.

Cheers, Florian

This bug seems to apply to firefox as well. Downloading tar.gz files results in corrupt archives as long as compression is enabled.

SetEnvIfNoCase REQUEST_URI .(?:gif|jp?g|png|zip|tar.gz)$ no-gzip dont-vary

fixes the problem.

Is this still an issue for you? What Ubuntu version do you use? Thank you for telling us!

Not anymore, thanks!
