Problem in file upload

Question

whenever i am uploading trying to upload file having size more than the size specified in maxRequestLength , browser is showing "webpage can not be displayed" . an someone please tell me how to solve this problem

Answer 1

Increase maxRequestLength value in your web.config file.

maxRequestLength indicates the maximum file upload size supported by ASP.NET. This limit can be used to prevent denial of service attacks caused by users posting large files to the server. The size specified is in kilobytes. The default is 4096 KB (4 MB).

See maxRequestLength on MSDN.

So, if e.g. the page you posted a file is Upload.aspx, the necessary section in web.config would be like this

<location path="Upload.aspx">
    <system.web>
        <httpRuntime maxRequestLength="{your value here}" 
                     executionTimeout="{your value here}" />
    </system.web>
</location>

Answer 2

Place this in your web.config

  <system.web>
     <httpRuntime executionTimeout="360" maxRequestLength="100000" />

That enables a 360 second timeout and 100,000 Kb of upload data at a time.

If that doesn't work, run this command on your IIS server. (replace [IISWebsitename])

C:\Windows\System32\inetsrv>appcmd set config "[IISWebsitename]" -section:requestFiltering -requestLimits.maxAllowedContentLength:100000000 -commitpath:apphost

That enables 100,000,000 bytes of upload data at a time.
