升级到IIS 7，现在大型上传失败(upgraded to IIS 7 and now large uploads are failing)

 我最近将我的经典ASP应用程序从IIS 6移到IIS 7.5，然后当用户尝试上传大量文件或大文件时收到很多抱怨。 
 
 做了一些研究后，我使用以下命令更改了maxRequestEntityAllowed， 
 
appcmd.exe set config -section:system.webServer/asp/limits.maxRequestEntityAllowed:"2147483647" /commit:apphost
 
 这立即解决了这个问题。 问题是，它在某个时刻停止工作，错误又回来了。 就好像设置被覆盖在元数据库中，但是当我检查ASP>限制部分中的限制部分时，新值是stil记录的。 
 
 如果我再次重新输入大值，则上传再次起作用。 这怎么被覆盖？ 
 
 我确保在web.config文件和app.config文件中设置了这个新值。 我已经多次重启IIS，当IIS处于关闭状态时，事件使用了上面的appcmd。 
 
 任何帮助将不胜感激。 

I recently moved my classic ASP application from IIS 6 to IIS 7.5 and then received a lot of complaints when users tried to upload a lot of files or a large file.
 
After doing some research, I changed the maxRequestEntityAllowed, using the following command,
 
appcmd.exe set config -section:system.webServer/asp/limits.maxRequestEntityAllowed:"2147483647" /commit:apphost
 
That immediately solved the issue. The problem is, it stops working at some point and the errors come back. It's as though the settings gets overwritten in the metabase but when I check the limits section in the ASP > Limits section, the new value is stil recorded.
 
If I re-enter the large valure again, the uploads work again. How is this being overwritten?
 
I have made sure that the this new value is set in the web.config file and the app.config file too. I have restarted IIS several time and event used the above appcmd when IIS was in a shutdown state.
 
Any help would greatly be appreciated.
