The HttpRuntime property in Web. config.

Configuration HttpRuntime can also let FileUpload upload a larger file , However, the settings are too large for a denial-of-service attack caused by the user passing a large number of files to the server ( attributes are described )

Property

Property	Options	Description
appRequestQueueLimit		The maximum number of requests that ASP. NET will queue for the application. When there are not enough free threads to process the request, the request is queued. When the queue exceeds the limit specified in this setting, the incoming request is rejected through the "503-Server Too busy" error message.
Executiontimeout		Indicates the maximum number of seconds that a request is allowed to execute before it is automatically closed by ASP.
Enable		Specifies whether the application domain is enabled at the current node and child node level. The default value is true.
	True	Specifies that the application domain is enabled.
	False	Specifies that the application domain is disabled. The application will not load in memory, and any client requests will result in an error with an error number of 404.
IdleTimeOut		Specifies how long idle time the application domain will be shut down. The default value is minutes .
Enablekernelmodecache		Specifies whether output caching is enabled. Currently, this property only works if IIS version 6.0 or later is installed. The configuration of the output cache and the type of request determine whether the content is cached. You must explicitly enable caching through page directives or using the cache API. cache must have an expiration policy so the kernel knows when to discard the cache. The cache cannot have any variable headers or parameters. request cannot require any authentication.
	True	Specifies that caching is enabled.
	False	Specifies that caching is disabled.
maxRequestLength		Indicates the maximum file upload size supported by ASP. This restriction can be used to prevent denial of service attacks that result from the user passing a large number of files to the server. The specified size is in kilobytes. The default value is 4096 KB (4 MB).
Minfreelocalrequestfreethreads		The minimum number of free threads that ASP. NET maintains to allow new local requests to execute. The number of threads is reserved for incoming requests from the local host, in case some requests make child requests to the local host during their processing. This avoids possible deadlocks caused by recursive re-entry into the WEB server.
minFreeThreads		The minimum number of free threads that are allowed to execute new requests. ASP. NET is a free State for requests that require additional threads to complete their processing.
useFullyQualifiedRedirectUrl		Indicates whether client-side redirection is fully qualified (in the {HYPERLINK "Http://server/path"} format, which is required for some mobile controls), or indicates whether a relative redirect is sent to the client instead.
	True	Specifies that client redirection needs to be sent in a fully qualified format. This is accomplished by automatically converting all redirects to a fully qualified format that are not fully qualified.
	False	Specifies that client redirection does not need to be automatically converted to fully qualified format. false is the default option.
Versionheader		Specifies the value of the version header that ASP. NET sends with each response. Microsoft Visual Studio. NET uses this property to determine which version of ASP is currently in use. This is not required for the product environment and can be disabled by removing the property from Web. config or machine.config, or by setting the property to an empty string (versionheader= "").
