Digging into Windows Server AppFabric tracking event collection service

mmpower Software June 3, 2012

There is no enough documentation for configuration of AppFabric Event collection service. The best doc I can find is this MSDN page:
http://msdn.microsoft.com/en-us/library/hh334438

We would like to fine control when workflow tracking events are being persisted. how ever, the document does not provide details of how extactly events are schduled to be persisted to the monitor datastore. The main configurable settings are the “eventBufferSize” and “RewriteDelay” attributes in root web.xml:

[民工日记]简单服务器GEO-Routing: 根据ip自动分流

mmpower Internet and Web, IT February 23, 2010

不通过应用程序而纯粹从服务器简单配置。。。transparent to your apps

1. 用 apache mod_rewrite 实现根据用户ip自动选择镜像

这是一个非常简单的实现–如果用户来自中国，自动重定向到位于中国的服务器，否则转到海外的服务器。并且自动检测服务器状态，如果一个服务器倒了所有traffic都会转到另外的server.

在 apache config 里加一个 virtual host:

ServerAdmin [email protected]
DocumentRoot /hosting/balance
ServerName balance
<filesmatch "\.(php|htm|html|pl|asp)"="">
Allow from all

RewriteEngine on
RewriteLog rewrite.log
RewriteLogLevel 9
RewriteMap lb prg:/hosting/balance/ip_prg.php
RewriteRule ^(.*)$…
