Confluence の組み込み gzip 実装よりも Apache mod_deflate を優先する

  1. Disable gzip in confluence. See Compressing an HTTP Response within Confluence.

  2. Apache で gzip 圧縮を有効にします。RedHat ディストリビューションでは、これは次の行を追加することで実現できます。 
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/x-javascript

# ensure sensible defaults
DeflateBufferSize 8192
DeflateCompressionLevel 4
DeflateMemLevel 9
DeflateWindowSize 15

keepalive が有効になっていることを確認する 

KeepAlive On

最近の MSIE ユーザー エージェントの keepalive を有効にする

The standard Apache SSL configuration is very conservative when it comes to MSIE and SSL. By default all keepalives are disabled when using HTTPS with MSIE. While MSIE will always be special, the issues with SSL and MSIE have been solved since Service Pack 2 for Windows XP, released over 4 years go. For anyone using an XP machine below SP2, it is safe to allow keepalive for MSIE 6 and above.

以下の行を削除します。

SetEnvIf User-Agent ".*MSIE.*" \
   nokeepalive ssl-unclean-shutdown \
   downgrade-1.0 force-response-1.0

その場所に以下を追加します。

BrowserMatch "MSIE [1-4]" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0
BrowserMatch "MSIE [5-9]" ssl-unclean-shutdown
