I`m using vs2008. I added a webform with the following code:
<form id="form1" runat="server">
<div>
<table>
<tr>
<td>
upload image:
</td>
<td>
<asp:FileUpload ID="FUImage" runat="server" />
</td>
</tr>
<tr>
<td>
</td>
<td>
<asp:Button ID="BtnUpload" runat="server" Text="Add" />
</td>
</tr>
</table>
</div>
</form>
and in cs file is nothing, except default pageload handler that is empty.
I run webapplication, , choosing a jpg file to upload, clicking add new button and see internet explorer can`t show the page specified message.
.NET can limit the size of requests to the server which obviously limits the maximum size of uploadable files.
http://msdn.microsoft.com/en-us/library/e1f13641.aspx explains the appropriate web.config attribute, in particular the maxRequestLength attribtue.
