I recently moved my classic ASP application from IIS 6 to IIS 7 and then received a lot of complaints when users tried to upload a lot of files.
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?
