On: Google disables compression for OpenSSL in Chrome - SSL exploit coming?

[caf]

It's a disabling of the optional compression at the TLS layer. HTTP content compression is not affected.

So what, exactly, is no longer compressed? Merely the headers themselves, and the content is not affected?

[caf → alanh]

Pretty much, yes. With the proviso that if you didn't have HTTP Content-Type compression for your content before, then it might still have been compressed at the TLS layer, and won't be now.
