maxRequestLength - Maximum request length exceeded

maxRequestLength - Maximum request length exceeded - IIS6

Describes some problems with IIS6 and upload of large files.

Symptoms

When you try to use the ASPForm object to upload a large file with ASP and IIS6, the file may not be uploaded. This problem occurs because the default value for the maxRequestLength parameter in the <httpRuntime> section of the Machine.config file is 4096 (4 megabytes). As a result, files that are larger than this value are not uploaded by default.

Resolution

To resolve this problem, use one of the following methods:

In the Machine.config file, change the maxRequestLength attribute of the <httpRuntime> configuration section to a larger value. This change affects the whole computer.

In the Web.config file, override the value of maxRequestLength for the application. For example, the following entry in Web.config allows files that are less than or equal to 8 megabytes (MB) to be uploaded:

<httpRuntime maxRequestLength="8192" />
