Avoid downloading files larger than 10 MB

Question

Is there any way (possibly a module) that can cause IIS7 to reject a message with a file larger than 10 MB?

My ASP.NET application has a download page, and the file cannot be larger than 10 MB, I believe that I can check the file size only after everything has already been sent to the server.

An IIS7 module would be the right choice for this, does anyone know one thing?

Answer 1

You can set the limit in Web.Config

<system.web> <httpRuntime maxRequestLength="xxxxx" executionTimeout="xx"/> </system.web> 

sidenote:

IIS7 rejects any file larger than 30 megabytes by default, you can enlarge it by adding the following code

 <security> <requestFiltering> <requestLimits maxAllowedContentLength="XXXXXX″ /> </requestFiltering> </security> 

If you want to get the size of the content before downloading, you can use the HTTP HEAD method to get the Content-Length.
