HttpCapabilitiesBase.RequiresUniqueFilePathSuffix Property
.NET Framework (current version)
Gets a value indicating whether the browser requires unique form-action URLs.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System.Booleantrue if the browser requires unique form-action URLs; otherwise, false. The default is false.
A self-referring HTML <form> element is one for which the action attribute specifies its own URL. If true, self-referring forms do not return the correct results. This is due to caching by either the browser or an intermediate gateway. To correct this, server control adapters append a default query string (__ufps=uniquefilepathsuffix) onto the form-action URL values of self-referring forms.
The following code example shows how to determine whether the browser requires unique form-action URLs.
