SharePoint BlobCache 报 Access Denied
今天突然发现微软Knowledge Base Article的ID号升级了, 从原来的六位变成七位了, 呵呵. 微软出KB文档还是挺快, 挺多的.

解决方案
==========
1. Use a different root blobcache folder for each application.
To work around this issue you can specify a different folder when configuring blob caching for each web application in the web.config.
<BlobCache location="DRIVE:\blobCache" path="\.(gif|jpg|png|css|js)$" maxSize="10" max-age="86400" enabled="True"/>
If you set the BlobCache locations to the following you should avoid this problem:
Web Application Location
First DRIVE:\blobCache
Second DRIVE:\blobCachetwo
Third DRIVE:\blobCachethree
2. Manually give <LOCALMACHINE>\WSS_WPG full control to DRIVE:\BlobCache.
3. Use the same app pool account for any applications you plan to enable blobcaching on.
