Configuring maxRequestLength for windows client application

[Stephen Ahn]

Given a web service method defined like this :

[WebMethod]
public string EchoByteArray(byte[] data)
{
return data.Length.ToString() + " bytes received";
}

If, from a Windows C# app, I call this web method with a 5000 Kbyte array,
I get an exception such as :

Exception : System.Web.Services.Protocols.SoapException -
System.Web.Services.Protocols.SoapException:
There was an exception running the extensions specified in the config
file. --->
System.Web.HttpException: Maximum request length exceeded. at
System.Web.HttpRequest.GetEntireRawContent()
at System.Web.HttpRequest.get_InputStream()
at System.Web.Services.Protocols.SoapServerProtocol.I nitialize()
--- End of inner exception stack trace ---
at System.Web.Services.Protocols.SoapServerProtocol.I nitialize()
at System.Web.Services.Protocols.ServerProtocolFactor y.Create(Type type,
HttpContext context,
HttpRequest request, HttpResponse response, Boolean& abortProcessing)

==
Now, I can change the maxRequestLength attribute in httpRuntime element in
machine.config,
and this makes the code work (since default is 4096 KBytes).

Is it possible to configure maxRequestLength in the application's config
file ?
(Remember that this is a Windows client app).
I tried changing the the <myappname>.exe.config file with settings which
looked
like this :

<configuration>
<system.web><httpRuntime maxRequestLength="50000"/>
</system.web>
</configuration>

but it seems to have no effect on the app - the setting seems to
get ignored completely.

Any ideas ?
TIA,
Stephen

No, the HTTP Runtime that's being configured is on the server.
The server is oblivious to the configuration files on it's clients.

It would rather undermine the point of allowing server admins to
specify a maxRequestLength (that point being to prevent DoS
attacks whereby miscreants tie up a server by submitting large
requests) if any hacker could simply set a larger value on their
client and bypass the server's setting, wouldn't it? :-)

Talk to the administrator of the server to increase the setting;
or re-design your requests to fit within your alloted bandwidth
by breaking the data up into chunks across multiple requests
and re-assembling them on the other end.

Thanks, now it makes sense.
I was getting confused, because I was testing on a PC which was
both the client and the server. Changing the machine.config file
on this PC had the desired affect, but I was thinking this
was effecting the client app, and not the server. (Obviously,
this was wrong).

You can set it in the web.config file with:
<httpRuntime maxRequestLength="8000"></httpRuntime>

The above will set it to 8 mb
