Eugenio,

Yes, there is a limit and it exists in order to prevent denial of service on a server with a slower connection. The setting for this limit is in the machine.config file, which can be found in:

%SYSTEM ROOT%\Microsoft.NET\Framework\v1.x.xxxx\CONFIG\

Look for the attribute maxRequestLength in the httpRuntime tag. The default value is 4096 which is 4 MB. You can change it appropriately.
