HeaderWaitTimeout

  • Article

The HeaderWaitTimeout property specifies the amount of time (in seconds) the server waits for all HTTP headers for the request (indicated by a double carriage return) to be received before disconnecting the client. The purpose of this property is to help prevent a common variant of the Denial of Service (DoS) attack that attempts to max out connection limits and keep those connections connected.

IIS 6.0: Use this property in conjunction with ConnectionTimeout and MinFileBytesPerSec instead of ServerListenTimeout for Web service nodes.
