The default size of the Windows credential handle cache.

Attributes
ConfigurationPropertyAttribute

Remarks

By default, the value of defaultCredentialsHandleCacheSize is 0. This causes Windows to allocate a separate SSPI handle for each HttpWebRequest.

<system.net>
  <settings>
    <windowsAuthentication defaultCredentialsHandleCacheSize="0" />
  </settings>
</system.net>

If this behavior impacts performance, set DefaultCredentialsHandleCacheSize to a value greater than 0 to use a single, cached SSPI credential handle for default network credentials. The exact value depends on application requirements. Generally, a value between 50 and 100 works for most high-performant applications.
