package downloads confuse IE6 and webkit-gtk browsers

[duncan]

In IE6 the .tar.gz packages from the Hackage website get downloaded and saved by the browser with the wrong name. For example foo-1.0.tar.gz gets saved as foo-1.0.tar.tar.

Currently the apache config for the hackage website is such that it send these headers for .tar.gz files:

Content-Type: application/x-tar
Content-Encoding: x-gzip

This apparently confuses IE6. This has been  reported elsewhere previously.

So we are looking for help in finding a workaround. We want to adjust our apache config so that for the IE6 user agent it reports a mime time and encoding that will make IE6 save the file properly. For example we guess that sending Content-Type: application/x-gzip and no Content-Encoding would make IE6 do the right thing.

So how do we actually configure apache to do this? Can we get some help testing it?

It's worth to note that some webkit browsers (epiphany) alter slightly this behaviour and saves uncompressed file unser name foo-1.0.tar.gz.
