    Does RadUpload work with the integrated pipeline mode of IIS7 (I see posts from several years back that it did not). It appears to work fine with the ASP.NET Development Server but once deployed to a test server running 2k8R2 IIS7 I get a 404 - File or directory not found when attempting a larger file upload. This file size would be large enough to trigger the upload progress bar. As far as I can see my web.config is fine, the only difference being that I'm running in 4.0 Integrated mode. I cannot (well it would be a major pain) go to using the Classic Asp.Net app pool and trying to use the 4.0 classic mode results in a failure as well. I'm running Q3 2011 of the Telerik Controls.

    Any help would be appreciated

    Hello Colin,

    There are some special settings that must be applied to the web.config in order to allow for large file uploads in integrated more. Please take a look at this help article and more specifically at the part describing the requirements for IIS7.

    Kind regards,

    Thank you for the response. I had actually managed to figure this out but the article helped confirm my issue. I had the httpruntime maxRequestLength and requestsLimits maxAllowedContentLength set to the same value. This incorrectly assumed that they where both in Kb. As I found out and confirmed by the article they are in Kb and bytes. What a nuisance.
