Maximum request length exceeded.

[Lloyd Dupont]

I'm experimenting with an upload file page.
I have a few HtmlInputFile on it.

While testing it, I selected a 12MBfile, click "upload".
I was think I am safe as (at last in the code) I don't upload file bigger
than 1MB.

At the top of my request there is a module where I access the request and
while querying a parameter:
string var = context.Request["param"]

I get the following exception:
===
System.Web.HttpException was unhandled by user code
Message="Maximum request length exceeded."
Source="System.Web"
ErrorCode=-2147467259
StackTrace:
at System.Web.HttpRequest.GetEntireRawContent()
at System.Web.HttpRequest.GetMultipartContent()
at System.Web.HttpRequest.FillInFormCollection()
at System.Web.HttpRequest.get_Form()
at System.Web.HttpRequest.get_Item(String key)
at LangModule.HTranslate(Object sender, EventArgs e) in

at
System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step,
Boolean& completedSynchronously)
===

What could I do to get around that?
I mean, I don't want to download 12MB file (I just skip the upload and write
a error status message) and I don't want them to cause my application to
fail....

Perhaps some Javascript?

The default maximumRequestLength is 4 mb. While ASP.NET can handle much
larger files, MS recommends a 10-20 mb limit for the files.

If you're using ASP.NET 1.1, try sticking this in your web config file
(16mb limit) somewhere inside of <system.web>

<httpRuntime maxRequestLength="16384" />

See:

In ASP.NET 2.0, you can set this dynamically at the page level.

This issue can be handled in Global.ascx file

In the Application_Event function of Global.ascx.cs file, put the following line:

Response.Close();

Then you will have your issue gone.
