This will be a quick link to help other folks with a problem I had with a
recent project.
If you need to upload a file that is larger than the 4 mb limit default in
ASP.NET, there is a great entry at Jon Galloway’s Blog. Go see his site for a great explanation,
but here is the solution in a nutshell.
Increase the maxRequestLength for the specific folder within your web site by
configuring the following setting in your sites Web.Config.
<location path="MyUploadFolder">
<system>
<httpruntime executiontimeout="110" maxrequestlength="20000">
</httpruntime>
</system>
