Hi,

We host multiple web applications on a shared web server, and due to the AspMaxRequestEntityAllowed value set to 1.5 MB one customer needs to allow image uploads to a greater size. I understand the concerns involved however, I know the property is at the web service level.

Is there any way I can restrict this property to a single app or can the customer can script this in his source code?

Yes you can set it individually per website by editing the value in the IIS metabase.

Do the following:

1. Open c:\windows\system32\inetsrv\MetaBase.xml in notepad
2. Find the website you want to change.
3. Add the new AspMaxRequestEntityAllowed value to that website.
4. I would recommend also setting the AspBufferingLimitt to match
5. Save and do an IISReset

Here's how it might look for the website in question (in the metabase xml file)...

<IIsWebServer      Location ="/LM/W3SVC/938724321"
            AspBufferingLimit="30400800"
            AspMaxRequestEntityAllowed="30400800"
            AuthFlags="0"
            LogPluginClsid="{FF160663-DE82-11CF-BC0A-EE00006111E0}"
            ServerAutoStart="TRUE"
            ServerBindings="50.63.148.126:80:www.TheDomainName.com
                  50.63.148.126:80:TheDomainName.com
            ServerComment="TheDomainName.com"
      >
</IIsWebServer>

As far as I know there is no way to do this programmatically on the fly.

I will implement this and let you know. However, is it possible to allow a week's time for me to accept this as a solution?

Hi,

I will be modifying the metabase.xml, before that I have a question.

The value for AspMaxRequestEntityAllowed property is currently set to '1572864' (which is the default at the web service level).
Will defining the variable at the web application level override the server level value?


Thanks
