Hi

I tyrd to upload files using HttpPostedFile.

Seems like there's a limit on the size of the file (Request?) of around
5Mb.

Anyone found a way to work around this, or increase the limit,

When I try a bigger file I get a DNS error in IE



Would seem to be some sort of server configuration issue.

Cheers

Hi All


i got answer For File Upload Size Limit in DotNet

By default ASP.NET limits the size of file uploads to
around 4Mb. This is to prevent denial of service attacks where people try to
bring down a server by launching massive files at it.
To enable support for larger files, i was added the following
configuration setting value to my apps (or machine's web.config file):

<configuration>
<system.web>
<httpRuntime maxRequestLength="4096" />
</system.web>
</configuration>

Note that the "4096" value above is the size in Kbytes that is configured
out of the box (in machine.config).

[We can change it to be whatever size we want.]

Thnx

thx

Hi there,


maxRequestLength attribute indicates the maximum file upload size supported by ASP.NET.

This limit can be used to prevent (DOS) denial of service attacks caused by users posting large files to the server.

The size specified is in kilobytes. The default is "4096" (4 MB). Max value is "1048576" (1 GB) for .NET Framework 1.0 and 1.1 and "2097151" (2 GB) for .NET Framework 2.0.

An attack on a network designed to render it - or an Internet resource - unavailable. The target may be an organisation's e-mail services or its website.

A denial-of-service attack (also, DoS attack) is an attack on a computer system or network that causes a loss of service to users, typically the loss of network connectivity and services by consuming the bandwidth of the victim network or overloading the computational resources of the victim system.
