Less than two hours ago, I found the page http://www.wikipedia.com/wiki/Sweden blank again. So I clicked Edit, then Save, to restore its full contents. This has happened before. See the page's History. Is this "the caching bug"? How does it work? Wouldn't the obsolete cached copy me destroyed the first time I did this? Why does the blank page come back? Is caching really necessary for performance now? When caching was activated, I thought several other functions were disabled at the same time. Do we know the impact on response times of not using caching? -- Lars Aronsson <lars(a)aronsson.se> tel +46-70-7891609 http://aronsson.se/ http://elektrosmog.nu/ http://susning.nu/
