Domino 6.0.1 introduces the use of Entity tags (ETags) for cache validation.
ETags, which were introduced in HTTP/1.1, are server-defined tokens that
uniquely identify multiple instances or versions of the same resource.
ETags can significantly improve server performance by increasing the effectiveness
of browser-side caching.
ETags can be disabled for diagnostic purposes via DominoDisableETags=1
When the NOTES.INI option DominoDisableETags is completely absent, or it
does not equal 1 then ETags are enabled.
Always leave ETags enabled. Completely remove any reference to DominoDisableETags
Introduced in 6.5.1
No restart is necessary. Changes to this setting are automatically detected.
