General Apache Configuration Notes
Prefer Apache mod_deflate to Confluence's built-in gzip implementation
- Disable gzip in confluence. See Compressing an HTTP Response within Confluence.
Enable gzip compression in Apache. For RedHat distributions this can be achieved by adding the following lines:
Ensure keepalive is enabled
Enable keepalive for recent MSIE user agents
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 SP2 or above, it is safe to allow keepalive for MSIE 6 and above.
Remove the following lines:
SetEnvIf User-Agent ".*MSIE.*" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0
Add these in their place:
BrowserMatch "MSIE [1-5]" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0 BrowserMatch "MSIE [6-9]" ssl-unclean-shutdown
