Does Pure ASP Upload 3 support uploading large files on Windows 2003 server? I'm getting the following error:

Request object error 'ASP 0104 : 80004005'
Operation not Allowed

Yes, Pure ASP Upload supports uploading large files on the Windows 2003 server. However:

IIS6.0 prevents the upload of files more than +200Kb. So you need to make some changes in the default IIS settings first.

Background

For IIS6.0 users, the AspMaxRequestEntityAllowed property specifies the maximum number of bytes allowed in the entity body of an ASP request. If a Content-Length header is present and specifies an amount of data greater than the value of AspMaxRequestEntityAllowed, IIS returns a 403 error response.

This property is related in function to MaxRequestEntityAllowed, but is specific to ASP request. Whereas you might set the MaxRequestEntityAllowed property to 1 MB at the general World Wide Web Publishing Service (WWW Service) level, you may choose to set AspMaxRequestEntityAllowed to a lower value, if you know that your specific ASP applications handle a smaller amount of data.

Solution

Open your metabase.XML which is located in c:\Windows\System32\Inetsrv find the line "AspMaxRequestEntityAllowed" and change it to "1073741824". This is 1GB - of course you can enter another value to suite your needs.

NOTE: Before you edit the file, be sure to stop the IIS service first or else you won't be able to save the file.
