Consider the following scenario. You have a Web site that is hosted on a server that is running Internet Information Services (IIS) 7.0. When a user visits this Web site, the user receives an error message that resembles the following error message:
Server Error in Application "application name" HTTP Error 404.13 - CONTENT_LENGTH_TOO_LARGE HRESULT: 0 Description of HRESULT# The operation completed successfully.
This problem occurs because the client request contains a Content-Length header that is larger than the value that is specified for this header in the maxAllowedContentLength property in the ApplicationHost.config file.
To resolve this problem, follow these steps:
Click Start. In the Start Search box, type Notepad. Right-click Notepad, and then click Run as administrator.
Note If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
On the File menu, click Open. In the File name box, type %windir%\system32\inetsrv\config\applicationhost.config, and then click Open.
In the ApplicationHost.config file, locate the <requestLimits> node.
Remove the maxAllowedContentLength property. Or, add a value that matches the size of the Content-Length header that the client sends as part of the request. By default, the value of the maxAllowedContentLength property is 30000000.
For example, modify the following configuration data inside the <requestFiltering> section.
