Jim Riggs <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Attachment #26333|0 |1 is obsolete| | --- Comment #6 from Jim Riggs <[email protected]> --- Created attachment 31503 --> https://issues.apache.org/bugzilla/attachment.cgi?id=31503&action=edit 2.2 thundering herd fix The attached patched was discussed and looked at by myself, covener, and mrumph today at ApacheCon. This fixes the thundering herd problem in 2.2. It also addresses r572626 (https://issues.apache.org/bugzilla/show_bug.cgi?id=30370) that created this regression. So, this patch fixes both the original problem in 30370 as well as this issue. It applies only to 2.2; >= 2.3 was fixed in r1023398. To summarize: without this patch, 2.2 has NO protection from the thundering herd, as the stale content is removed before being refreshed. Thus, all subsequent herd requests have no stale content to serve and flow through to the backend. Should the documentation be updated also to alert users to this? That is that "2.2.x before 2.2.__ is not protected from the thundering herd"? -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
