Maximum request length exceeded.

 

 

If you are using IIS for hosting your application, then the default upload file size is 4MB. To increase it, please use this below section in your web.config -

<configuration>
    <system.web>
        <httpRuntime maxRequestLength="1048576" />
    </system.web>
</configuration>

For IIS7 and above, you also need to add the lines below:

 <system.webServer>
   <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="1073741824" />
      </requestFiltering>
   </security>
 </system.webServer>

Note:

• maxRequestLength is measured in kilobytes
• maxAllowedContentLength is measured in bytes

which is why the values differ in this config example. (Both are equivalent to 1 GB.)
