As I informed earlier we made a major move to a new server in the last few days.�����ҸղŸ�������������һ���ش�ٴ뵽һ���µķ������ڹ�ȥ���졣 All the websites have moved over.���е���վ����� There was lots of testing.�д����IJ��ԡ� What surprised me was that most of my tester's were getting a stale copy of the pages, despite page refresh and clearing of cache.��ʲô��֣������Ҵ󲿷ֵIJ����ǵ������¾ɵĸ�������ҳ����Ȼ��ҳ�������?������Ŀ�ȡ�����塣 It turned out to be a DNS caching issue with Analog X Proxy server.���ݱ��һ��DNS��������⣬��ģ��x�����������

Analog X provides a nice proxy server for free.ģ��X�ṩ�����õĴ������������ѵġ� Today I realized it also caches DNS data (host name to ip address mapping) for free and for unknown (but pretty long) duration.���죬��ʵ������Ҳ����DNS��ݣ�������IP��ַӳ�䣩Ϊ���ɺͶ�δ֪�����൱���ģ�ʱ�䡣 So if you are using Analog X proxy and are unable to access any webserver then it may be that you are getting served from a stale IP address by AnalogX.��ˣ��������ʹ�õ�ģ��x Proxy���޷�����κε������������Ȼ������������÷��񣬴ӳ¾ɵ�IP��ַanalogx �� There is nothing wrong with DNS caching.��û��ʲô���׵�DNS���档 Lot's of application like Agnitum Firewall caches DNS data.�ܶ��Ӧ��һ�� agnitum����ǽ����DNS��ݡ� In fact it is a benefit in normal circumstances as it speeds up web access and prevents loading of DNS servers (which caches the data too).��ʵ�ϣ�����һ���츣����������£���Ϊ��ӿ�Web Access�ͷ�ֹװ�ص�DNS�ŷ��������а��ص����̫�� �� The problem is because AnalogX proxy server doesn't advertise it anywhere and provides no way to disable the cache.�����ǣ���Ϊanalogx���������������棬�����κεط������涨û�а취���û��档

The solution is simple.����취�ܼ򵥡� Simply restart the Analog X proxy server.�򵥵���������ģ��x����������� It appears to clear the cache.�����������档
