I have to upload a file like 1 Gb or more than it have to upload.

but currently, only 241 MB file can upload more than it fails to upload.

In a webconfig I add code for upload large file.

Please give me hint where I am wrong.

What I have tried:

<system.webServer>
    <security>
      <!--<requestFiltering allowDoubleEscaping="true"/>-->
      <requestFiltering allowDoubleEscaping="true">
        <!-- This will handle requests up to 3000MB (3GB) -->
        <requestLimits maxAllowedContentLength="3000000000" />
      </requestFiltering>
    </security>
  </system.webServer>

<httpRuntime targetFramework="4.5.2" executionTimeout="9999" maxRequestLength="2097151" />

maxRequestLength[^] is measured in kilobytes and maxAllowedContentLength[^] is measured in bytes. They have to be equal.

For 1GB it would be:
web.config:

HTML

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

IIS7 and above settings:

HTML

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

See:

How much is 1 byte, kilobyte, megabyte, gigabyte, etc.?[^]
