Hi All,

Environment: Windows Server 2K3, IIS 6.0, ASP.Net 2.0, Intranet site

Requirement: Site has to provide interface to upload 100 MB - 650 MB files on the web server (or file server).

Problem: Client has got few more sites hosted on the IIS and client has restricted the file size (to be uploaded) to 2MB. Client do not want to change this setting on server.

Considering the above scenario
1. Can we change this setting for a site on IIS? (instead of affecting the server can we change it for a particular site)
2. Can we change it programatically?
3. Any work around to this?

Please help urgently.

Thanks a ton in advance.

Best regards,
Rajesh Khatri

Hi Rajesh -
No,There is no way to restricted upload size limit only for a site in IIS becuase it operate through
through 'metabase.xml' file.You can restricted ASP upload size for all site through 'Merabase.xml' file

Steps :

Go to 'C:\WINDOWS\system32\inetsrv' and find 'Metabase.xml' file
Search text "AspMaxRequestEntityAllowed="204800"
And assigned size limit.

Warm Regards,

shambhusingh2004 is right, but AspMaxRequestEntityAllowed only works for ASP code. If you are using ASP.NET 2.0, you can put the limit programmatically. By default, the limit is 4mb for the FileUpload Control.

Working Around File Size Limitations

You may not realize it, but there is a limit to the size of a file that can be uploaded using this technique. By default, the maximum size of a file to be uploaded to the server using the FileUpload control is around 4MB. You cannot upload anything that is larger than this limit.

One of the great things about .NET, however, is that it usually provides a way around limitations. You can usually change the default settings that are in place. To change this size limit, you make some changes in either the web.config.comments (found in the ASP.NET 2.0 configuration folder at C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG) or your application's web.config file.
