Increasing the maximum upload limit on a Sharepoint Site

I found this on a blog  from Mark Rhodes (http://www.msexperts.org/blogs/mark/archive/2008/10/23/increasing-the-maximum-upload-limit-on-a-sharepoint-site.aspx)
You need to do 3 things to be able to increase the limit of upload.

1.  Increase the Web Applications Upload limit.
2.  Increase the HTTP Timeout.
3.  Increase the Execution Timeout and MaxRequestLength in web.config

1. Increase the Web Applications upload limit

Open Central Administration. Go to “Application Management”, then “Web Application General Settings”.  Ensure you are on the correct web application and modify the “Maximum Upload Size” field.

2.  Increase the HTTP Timeout

Open IIS, find the appropriate website and open its properties.  The timeout setting is on the Website tab and in the connections setting under “Http Connection Timeout”.  I’d probably consider adding 120 seconds per extra 50 mb, more or less depending on your connection.

3.  Increase the Execution Timeout and MaxRequestLength in web.config

Edit C:\Program Files\Common Files\Microsoft Shared\Web server extensions\12\TEMPLATE\LAYOUTS\web.config

From :

<location path=”upload.aspx”>
<system.web>
<httpRuntime maxRequestLength=”2097151″ />
</system.web>
</location>

To :

<location path=”upload.aspx”>
<system.web>
<httpRuntime maxRequestLength=”2097151″ ExecutionTimeout=”999999″/>
</system.web>
</location>

Edit the web.config in the home directory of the IIS Site of your web application.

From :
<httpRuntime maxRequestLength=”51200″ />

To :
<httpRuntime maxRequestLength=”51200″ executionTimeout=”999999″ />
